When a girl is squatting down giving a guy a blow job, and right before he cums, she loses her balance, falls off, and gets squirted in the eye on as she falls backwards!
That poor drunk girl was blowing me in the bathroom but had no idea she was in for a pirate cumsquat!
n. An item of clothing which has been spooged upon, and then continues to be worn without being washed.
I can't believe that groupie left a cumshirt in her laundry for two weeks and kept looking at it as a reminder of being bent over by a second-ratebassist.
