Rap star Boosie Badazz is coming under fire, and he's currently trending on social media.

Last night, the rapper attended an NBA game, wearing a red Kappa Alpha Psi sweatshirt and the organization is not happy about it. 

Kappa Alpha Psi, is a historically Black fraternity with a special membership process and one that is heavily active on college campuses across America.

It's a proud organization which boasts famous members like the late Reginald Lewis, the first black billionaire, Bob Johnson billionaire businessman and founder of BET, Bill Russell, former NBA player and first African American to be inducted into the NBA Hall of Fame, the late John Singleton, Hollywood movie director best known for Boyz n the Hood and the Fast & Furious, and political commentator, Marc Lamont Hill.

Thus the organization holds its membership sacred and does not allow non-members to wear its logo.

Last night Boosie said "f*ck that" and wore the sweatshirt anyway.

The rapper posted on IG a pic of himself wearing their apparel at the game. Afterwards his comments were filled with Kappas asking Boosie to remove the sweater. They claimed that they felt "violated" by the rapper.

Boosie then went on Live and said "f*ck Kappas." He also told the fans that he will wear whatever he wants.

Now many Kappas online are now claiming that they plan to "run down" on Boosie when they see him.

Here's Boosie, wearing the sweater:
