Also known as "Slobbery Long Jawn".

After receiving a blow job from a girl on the top bunk of bunk beds, the act of jumping down to the ground in such a way that your slobbery, erect penis slaps the person occupying the bottom bunk in the face.
Now you are really gonna get it... I was only going to shroom slap you, but now I'm going to give you a slobbery long john!
