The Chainsmokers have made one clothing company sick to their stomach over the band's use of the phrase "Sick Boy" on t-shirts and sweatshirts ... so much so they are now suing over it.

According to court documents obtained by The Blast, a company called Sick Boy claims they trademarked "Sick Boy" for various clothing items back in 2001. They claim rockers such as Guns N’ Roses, Van Halen, Ratt, Motley Crue, and Quiet Riot have all worn their gear.

But Sick Boy claims in 2018, The Chainsmokers released a song called "Sick Boy" and soon began offering clothing on their site bearing the name. They claim they sent cease and desist letters to both the band and Live Nation — who runs their online site — but nothing changed.

Sick Boys claims they have been "deprived of sales of products and services and has suffered a diminution of the value" of its brand as a result of the alleged infringement. They say they have suffered "irreparable harm" and will continue to do so unless the court steps in.

They are suing for trademark infringement and seeking unspecified damages.

The Blast reached out to the band for comment — so far, no word back.
