Guacbruh

A Guacbruh can be used as a compliment or an insult, depending on the tone of your voice. A guacbruh is a bruh (silly person) who is mashed up, so basically retarded and has 3 braincells. If you use it as a compliment, you say it after they have done something really funny. If it a insult, it's used after they do something dumb and unfunny.

Gethin: Watch me poo in my mouth.

Gethin: *smashes my head into wall*

Me: *Becomes immortal because I called him a quacbruh*
