Emo Kid Compliment

Alright listen up, you silly goose. This "joke" is all about wordplay. The emo kid says, "I like ya cut, G," which sounds like "I like your cut, G." "Cut" can refer to someone's hairstyle, but in this context, it's also slang, shortened from "cut g" which is a friendly greeting. It means "I like your style, friend."
