Nick was cornered and tortured last night at the bar by that Shamu.

A girl who is at first sight cute, but at a closer look, she turns out to be ugly. She is friendly, but has a voice that will make you want to kill yourself, hence the fact that the whale Shamu squeaks. She is not a terrible person to be around, but gets jealous very quick if you ditch her for her hot friend. She is easy to get pissed off and is a slut to guys that she would only go out with just to get them to like her. At parties she will throw herself at guys, and pretends to be drunk so she can cover up how easy she is to get. Mainly found in high schools all around America.
Person 1: "Bro, look at that girl, shes hot!"
Person 2: "Are you kidding, shes ugly!"
Person 1: "Dammit, its just another Shamu."

Person A: "Yo, Amy told me she wants to hook up with me at the party on friday"
Person B: "Are you kidding! She told me that she didn't want to hook up with anyone! What a fucking Shamu!"
