literal definition is someone who takes credit for someone else’s fart
Also someone who steals your thunder or someone who takes credit for someone else’s work
I worked so hard on that project and Vincent stole all the credit even though he hardly did anything. He never even mentioned my name. He’s such a fartnapper!
A group of people that rolls 600 pounds deep, which is really no different than if one person acted like the 600 pound gorilla all by themself, it's just bullying spread around a group to fuck with somebody. Just like each person has an asshole, and to some degree is an asshole, a collective 600 pound gorilla has a collective asshole so that no one person has to take responsibility for being the asshole or the one who said this or that.
