Slowsturbation 

The act of masturbating slowly to increase duration and pleasure.

Going to the movies sounds cool man, but I'm gonna go home, make a sandwich, and get in a little slowsturbation.

The act of slapping your own male genitals to the point of seminal secretion

Hey man! I spent all last night participating in slapsturbation to wonderful pornography, and now my penis is shaped like a question mark!
