The Chi Omega sorority at Penn State is in serious trouble after posting a photo of themselves at a Mexican-themed party, according to Onward State. The photo is being circulated around the internet and being called racist and stereotypical.

A picture was posted on Tumblr and Facebook in what was called a “Mexican fiesta” themed party that happened around Halloween. The connection between Chi Omega and the picture was evident through tags and other posts regarding the party.

Girls were dressed up in ponchos and sombreros while wearing fake mustaches. Signs were held that read “Will mow lawn for weed and beer” and “I don’t cut grass, I smoke it.”

The sorority’s president Jessica Riccardi, told the the Daily Collegian that the sorority is under investigation. She also issued this apology:

“Our chapter of Chi Omega sincerely apologizes for portraying inappropriate and untrue stereotypes. The picture in question does not support any of Chi Omega’s values or reflect what the organization aspires to be.”

Cesar Sanchez Lopez, Vice President of the Mexican American Student Association, issued a statement regarding the situation, according to WebProNews.

“The Mexican American Student Association is disappointed in the attire chosen by this sorority. It in no way represents our culture. Not only have they chosen to stereotype our culture with serapes and sombreros, but the insinuation about drug usage makes this image more offensive. Our country is plagued by a drug war that has led to the death of an estimated 50,000 people, which is nothing to be joked about.”

The school is currently investigating the matter and will decide if punishment or further action needs to be taken.
