A big red zit with a big white tip. Squeezing causes a massive & violent eruption of ketchup & mayo.
Mark was going to ground and pound poor Danny Dork, but, Danny Dork squoze the ketchup & mayo volcano that was on his own forehead and shot the zit-based condiments into Mark's eye and mouth causing Mark to instantly scream and run to the boy's bathroom.
I guess Danny Dork won that fight. Now no one fucks with him. Zit Man!
