A very rare condition that is caused by listening to Lil Pump, where the individual believes that they are from the "Hood", and that they are a "Gangsta".
Some symptoms include false claims about
being black, when they are clearly white, and claims that their sister's,
cousin's,
Baby Momma got shot.
"Hey man, did you listen to
Lil Pump's new song?"
"Nah man, I've
heard that shit causes Pumptism, you should stop listening to that
rubbish."
