A derisive term used to describe the styling of the 2010 BMW S 1000 RR motorcycle. The bike features an ill-matched set of design elements which includes one round headlight paired with one triangular headlight, and large "fish gill" shaped vents located in Japanese-styled bodywork.
Man, that new BMW is fast, but the designers must have been dropping acid to dream up the dastardly monocle shark.

Was about to bang 30 year old mud shark at the bar then came to and realized it was 1:30am and I should go home.

A guy who will lend you money when no one else will, but extort you in interest and totally kick your ass if you don't pay.

When a man is erect and bends backwards on all fours and walks around with his "dorsal phin" in the air. "You may make noises while doing so". It can be done alone but preferred you have a partner to chase around.
Last night my boyfriend started shark attacking me. He wasn't fully erect so it looked more like Free Willy's fin.
