1. Sort of like a crude synonym for "thunk", it is a very rough,
illiterate term to hit or brutishly yet carelessly cuff them with the side of a hand or fingertip.
2. A Thwomp is one of the classic
Mario Bros, usually found in the Bowser Castles. They come in various different sizes, and are enemies that cannot be defeated at all with neither a jump, Koopa shell, or fireball. If Mario comes near, then it comes crashing down on the
designated spot. The best way Mario can get past it is to run/dodge while the angry, strained-looking Thwomp is in the process of moving back up to it's original spot.
