Shaq's lame record label, an acronym for "The World Is Mine".

Also, what you yell out when you jump up and hang on a lowered rim in the gym, or maybe even the occasional doorframe lintel. Be sure to slap the backboard/wall before landing for full Shaq-ish goodness.
TWIsM records went out of business, which should come as no surprise to anyone who has heard Shaq rap.

When Brandon TWIsM-ed on that double-door's frame, he broke the spring mechanism clean off and had to run away from the vice-principal to avoid being caught.
