While someone is sleeping you sneak into their room and put their hand on the dick like they've been wanking. Works best if someone is sleeping with them so they'll see.
Wife: "WHAT why is your hand on your dick have you been WANKING!"
Husband: "No i don't wank! *breaks down*"
Prankster: "YOU JUST GOT WANK PRANKED!!"
Husband: "No i don't wank! *breaks down*"
Prankster: "YOU JUST GOT WANK PRANKED!!"
