3.
(n.) someone AND anyone who eats 'compota' (Gerber baby food) out of dirty vaginas

Special Note: Derived from CompUSA, it sounds really offensive in Cuban Spanish. And basically everything in Cuban slang sounds offensive.
Fulanito X: "Meng, I love me some compota."

Fulanita Y: "I bet you like dirty vaginas, too."

Fulanito X: "Ey, meng, punami is pumani."

Fulanita Y: "Wow, you're such a compusa."

Fulanita Z: "Hey! My vagina is clean!"
