Laughing so hard you piss yourself. Laugh + piss = Lissing.
The new comedian at the Comedy Club had me lissing all night long!

What lissing actually is is a cross between intimate kissing and licking
You go in for a loving smooch but, in the final second, turn the move into a lick hence 'lissing' !
