A Baylor University fraternity has been suspended over its 'racially insensitive' 'Mexican' themed party which saw some guests dress as maids, construction workers and even don brown face.

Skye Thomas, a freshman at Baylor who attended the 'fiesta themed' off-campus Kappa Sigma party in Waco, Texas on Saturday.

But when she arrived, she was shocked to find people 'dressed up so offensively' in mocking stereotypical costumes. She described seeing several guys dressed in bright green construction vests and another who was wearing 'brown face.'

The party has sparked outrage after photos of the event were posted on social media

'Why do you think it's okay to dress up like stereotypes of Mexican culture?!' she tweeted after the party, 'It was beyond offensive.'

Others on social media claimed to have heard the frat boys chanting 'build a wall' although Thomas could not confirm those claims.

While Halley Yzquierdo, who wrote a critical post about the 'ignorant' party after attending it on Saturday, said a frat member had responded saying the fiesta was still going and she was 'free to join the cleaners.'

'I just wanted everyone to see how suddenly I've been subjected to being a house keeper because of my race,' she said, posting the exchange.

'I understand that this party may not have been thrown with the intent of marginalizing a specific group, but with the recent election, I feel it is crucial that we do not proliferate discrimination based on societal misconceptions,' Yzquierdo wrote in a letter to the university, urging the university to expel the student who was allegedly wearing brown face.

The university is now investigating the 'racially insensitive' party and the frat chapter has been suspended

The racially insensitive party sparked a protest, organized by NAACP and LatinX Coalition, to call for change in the school.

Baylor vice president of student life, Kevin Jackson, described the behavior as 'deeply concerning. '

'We do not tolerate racism of any kind on our campus.'

A spokeswoman said Baylor University is now investigating the incident and said they were taking the matter seriously and have taken 'established disciplinary procedures'.

The national Kappa Sigma chapter added that they had suspended all operations of the Lambda-Tau Chapter at Baylor University after learning of the party while they launch an investigation.

'The allegations are inconsistent with the values of Kappa Sigma and upon the completion of the investigation, the Fraternity will address the findings in an appropriate manner. '

The party has sparked outrage after photos of the event were posted on social media.

Skye Thomas, a freshman at Baylor who attended an off campus Kappa Sigma party on Saturday, tweeted. along with many others, that she she was shocked to find people 'dressed up so offensively'

One Twitter user, who said he was of Mexican heritage, was furious that the fraternity had exploited his culture while holding it in contempt.

'So kappa sig threw a 'Mexican' party? yall are bold to yell build a wall but quick to have my culture as a theme for your wack a** party,' he said.

Thomas told Buzzfeed that while she had not heard the chant at that party, it was a regular event for the frat,

'Apparently, they have chanted 'Build the wall' before and then threw a party to 'celebrate' a Mexican holiday, so that is one of the reasons many people were hurt by it,' Thomas said.

'White people dressing up as maids and construction workers to celebrate their holiday is not [cool]' one Baylor student said.

'#DearKappaSig one man's culture is not another one's costume,' another tweeted.

A few tried to defend the frat on Twitter saying that people had simply been trying to celebrate Mexican culture for Cinco de Mayo.

'White people dressing up as maids and construction workers to celebrate their holiday is not [cool]' said one student - who was among dozens who complained about the party on Twitter

'All people did was dress up...for a cinco de mayo party,' one tweeted,.

But others shot them down saying party-goers decision to focus on negative stereotypes of Mexicans, such as portraying them as only having low paid jobs such housekeepers and constructions workers, was racist,

Baylor has come under fire for their attitudes towards racism in the past, after a black student complained a white student had pushed her and told her 'no n****rs allowed.'

The university has also been in the news after Baylor officials were heavily criticized for failing to properly respond to a series of rape and sexual assault reports on campus.

The scandal last year eventually saw local Phi Delta Theta chapter president Jacob Walter Anderson jailed on a sex assault charge.

It is not the first time a college has got into hot water for mocking Latino and Mexican culture.

In 2014, Chi Omega's national organisation shut down its Penn State chapter after a photo was circulated showing members dressed in an offensive parody of Mexicans.

It showed the sisters of Chi Omega at Penn State wearing sombreros, ponchos and fake moustaches while holding up signs saying 'will mow lawn for weed + beer' and 'I don't cut grass I smoke it'.
