H-upmann

When a girl (or guy) is performing a hand job, when the guy is about to ejaculate (explode, bust) she/he aims the penis back up at the guy's face, and hilarity ensues.

Joe: "Dude what's all over your face"

Jim: "Man all I can is H-upmann"

Joe: "You know, Sarah always struck me as the H-upmann type of girl"
