slobknocking

The act of spitting or drooling on someones penis, excessively during oral sex. Slobknocking is usually looked upon as something that needs to be done before sexual intercourse so the penis is lubricated enough to go in.

Or could also refer to the act of kissing with extreme amounts of saliva entering the other persons mouth or going on the other persons face.

Dude, Sally is fucking pro at slobknocking.

She made my penis so slippery we couldn't get the condom on.
