The religion of new lil pump (and his squadmembers) fans that hear one song and become the ultimate wannabe rappers. They try to act 'cool' or 'gangster', always screaming shit like "skrrah" or "prrt" and want to to dress like the rappers. Theyre most commonly found in social media, posting selfies where they use hand gang signs and comment the lyrics of their Gods songs. Most of them are white 13-16 year old kids who are (believe it or not,) actually harmless.
Oh lord, Pumptism has spread fast in our school. Look at them! Theres no place on earth thats safe now.
