When you ejaculate a massive load on someone in a repeating linear pattern to form a perfectly large rectangular patch, then top it off with sprinkles, similar to the frosting of the well known American snack Poptarts.
Guy 1: Dude, after not seeing her for the last month, I can't wait to Cumtart my girlfriend when she gets back from study abroad.
Guy 2: Totally bro, last week I put a bowl of sprinkles on the night stand and when i was about to cum, I asked my GF to pass the sprinkles and yelled "1 Cumtart coming up" while i busted on her and threw a fist of sprinkles all over her stomach.

When you get a hand job, with an armpit instead of a hand, and you cum in between the arm and pit. Slam it together and there’s a cumtart.
