He is the kindest person you will ever meet. His every feature is perfected and has no flaws at all. His best friends are always there for him just as he is to them. He is the best person you will ever meet and would drop everything just for one person. He is very special to some people (one person in particular) and his friends would do anything for him. Hes so stunning that his looks would turn the straightest man gay. Every girl wants to be with him and every boy wants to be him. He treats everyone like a Queen or King and if you are special to him you are the luckiest person alive. You will never meet someone like him so cherish every single moment you have with him. NEVER take him for granted.
~ Shamus means a lot to a girl he knows everything about, apart from her feelings... ~

The large girl at a bar or club that dances like she is the front runner for "So You Think You Can Dance" and hogs the dance floor or jumps up on the bar or table dancing like a trashy individual, but thinks she is God's gift to mankind.

Also the Killer whales at Sea World, but in a nightlife context refer to above definition.
Nick was cornered and tortured last night at the bar by that Shamu.
