a small, cone-shaped turd, most commonly encountered stuck to the "head" of one's penis during withdrawal from an unclean anus.
"As I pulled my cock from her chocolate starfish in anticipation of shooting my load onto her bare butt-cheeks, I noticed a smelly DUNCE CAP adorning my head. Too late to stop, my load propelled the DUNCE CAP like a stinky poo rocket ship square into the back of her head, knocking her unconscious."

Whilst drinking margaritas, the first person to get inebriated and show any type of misconduct verbally or otherwise must put their margarita glass over their head and have their photo taken. The first recipient to be shamed by this action was a house cat named Quincy, who was livid about the dunce cap being placed upon his head.

A cunt burger. Someone so unbelievably stupid they may as well be named Mordecai or Emily. A sub-human to the extent of being compared to an inanimate object. Basically, a chair so lazy and idiotic it would need to lie down before being used and subsequently break itself
Emily: I can't believe people don't like pickled lettuce on their pizza.
Sam: You fucking human dunce-cap

When a party foul occurs during an orgy the party fouler is required to sit in the corner, preferably on a stool facing the wall, with a conical stool (fecal) on their head while the men take turns jizzing on the individual's head.

"Dunce Cap Redemption" is the art of still managing to hook up with someone despite an obvious injury on your face, mostly likely occurring after a night of drinking. For example, a black eye from falling, or your best friend punching you. Or a head injury from getting scraped by a wall or tree branch. It requires great courage to express interest in a girl knowing she's looking at the stupid-ass self inflicted marks on your face, and winning her over in spite of looking like a dumb asshole is a significant event. It doesn't wash away your recent stupidity, but it sure does increase your confidence.
Bro #1: "Bro, is Justin really going home with her despite that gnarly wound on his face?"
Bro #2: " Dunce Cap Redemption at its finest".
Bro #3: He's still a dumbass though"

A dunce cap is a hat you can’t remove from you characters head in Grand Theft Auto 5 Online, it will be removed when you are I longer a bad sport or not in a bad sport lobby (how you get the cap in the first place) you will sometimes see someone with a dunce cap in a clean player lobby they have that because they did an outfit glitch to keep it with the outfit they had on in the bad sport lobby.
