The act of two men sitting on each others lap, face-to-face, while on the toilet and each person is taking a dump. At the end of such poopage, each man pee's upward into one anothers face.
I walked into the bathroom the other day and saw Bill and Matt blarrying each other.
Man, Frank really got a lot of pee in my eye at the end of our blarrying the other night.
Ray really blarry'd the shit out of me the other night.
