Northbridge’s Brass Monkey hotel has been on the end of a social media smashing after hanging sexually suggestive and sexist signage to promote a New Year’s Eve Frat Party.

Among the milder suggestions were signs saying “daughter drop-off point” and “we want your freshmen daughters”, with a “we want your freshmen sons, too” apparently thrown in as some kind of counterpoint.

The signs are similar to those erected at a United States university last year, which also caused outrage at the time.

"You've lost my and my friends' business until you permanently take down the misogynistic banners and publicly apologise for putting them up,” said one post.

The hotel’s page then posted this apology, which has so far received 134 comments and 11 shares.

The rating of the hotel’s page has already dropped 0.6 points, from 3.7 to 3.1 out of five. The number of one star reviews now outweighs the number of five star reviews.

The manager declined to comment to The West Australian.

A spokesman for ALH Group, the owners of The Brass Monkey, apologised for any offence caused.

He said an ALH Group representative had spoken to hotel management.

“The banners were inappropriate,” the spokesman said.
