The Harry Potter (n. & v.):

Occurs when, during a three-some, a female is jacking off a male. Right before he's ready to culminate, she yells "Alakazam," quickly turns the cock and, in a wand-like motion, yanks it so it blows all over the third member.
I got squirted in the face by the Harry Potter last night.
