1.
To eat with the loudest possible decibels and most disgusting mouth action ever know to man kind. Usually children owned by parents without table manners. Also a favorite of the elderly in community cafes. On rare occasions you will witness yopping by upstanding pillars of the community who often 'disappear' a few weeks later under mysterious circumstances.
You're yopping. Stop at once, move at once or prepare to be harmed.
