Laugh-N-Pass, A common tactic of smoke who does not want to smoke.
What is it? The person that never smokes, rather waits till everyone is laughing then passes at the end of the laughter.
Kevin didnt want to smoke so he waited until everyone busted out laughing. During this time he also laughed and then passed the blunt when everyone was done, completing the laugh-N-pass. During the laughing no one payed attention and figured he had smoked during that time.
