One of the coolest girls alive. Always fun to be around. Make great sisters and friends. Susies are usually funny, smart, nice and energetic. Crazy at times. Throws great parties and is overall one of the best. If you know one or have one as a sister consider yourself lucky!
Jimmy: Who's that awesome girl?
Fred: I don't know, she must be a susie.
