Group-based, uncontrollable laughter, (sometimes herbally induced), that goes on and on and just when you think it's over, it starts all over again. Often seen on blooper reels.
First guy: Why are all those people rolling around on the ground laughing?
Second guy: Who knows. Looks like they got a bad case of the schmoits.
