A SIMP is a person that worships the opposite gender, usualy being a guy worshipping a woman, to get their attention and love and calling them stuff like "queen" or "princess" etc. by doing almost anything, most of the time donating a large amount of money.
sidenote: a SIMP is not persone in a relationship, a guy having a girlfriend does not mean he is worshipping her which means he is not a simp.
friend1: hey wassup "friend2", sorry i couldnt call you yesterday i was watching this streamer and i donated her 500 dollars and SHE SAID MY NAME!!!!!!!
friend2: you are a SIMP
