Basically to be a dumb fuck. Common insult by anyone with an IQ well more than room temp. Used to degrade imbeciles who attempt to act superior than the intelligent (IQs over 110 IMO). I don't particularly enjoy talking with said idiots past simple things but I do enjoy manipulating them with basic derka derka psychology.
Moron: lol ur so stupid you don't act like me I'm "cool"
Me: cool story bro. I don't have time for 100 pound smart asses with room temperature IQs with homoerotic hair. Go suck on your stubs you lose. Miserable.
