When you come in your hand and then smack the girl across the face.
I sloppy handed her hard last night.

When one ejaculates onto ones hand and slaps the girl/guy across the face with that hand after a blowjob. Done best when recipient does not know it is going to happen.
Vijay sloppy handed her so hard, she fell over.
