Dickey Small Brains-- A fucking idiot. Somebody who constanstly partakes in fucking up. Being a clumpsy goober; acting like you know what you are talking about; being full of shit and completely believing the utterly repulsive garbage falling out of your face.
Dewayne: "All that hip-hop ruckus can suck my nutsacks"
Brad: "Did this guy just say nutsacks? As in multiple sacks?"
Ryan: "Yes, what a dickey small brains."
