splaknook 

This refers to when you jerk off in your hand and fling your wad onto your sleeping girlfriend's back.

Joe: Did you do anything last night?

Dave: No, just went home and splaknooked my girlfriend.

splagook

when there is no pressure behind a man's ejaculate.

When all the men in the bukkake circle can shoot their load on the girl except for the one guy whose load immediately just falls to the floor. He splagooked.
