Dumbcluck is A highly stupid individual that possesses tendencies that make him the closest thing to a dumbfuck. He will often seem like a bro to you, but don’t let this fool you. Dumbcluck is only out to steal your girlfriend and get pictures of them together snogging.

Person 2 - Yea man, your girlfriend was all over him while you were gone
