look up any word, like bias:
A cute girl, who is very smart. A Chelsi has swag. She is fly, crazy, fresh, ditzy, beautiful, gangster, barbie, diva, fun, irritating, badass, playertastic, indescribable; a Chelsi is a young lady who always looks her best. Not many can handle a Chelsi.
Damn, did you see Chelsi today?" "Yeah bruh, shes lookin fine as always and she has mad swagg."

A pretty girl that is a sexual dynamo and loves to please her man. She tends to over react, is loud, and is very happy but you can tell when she's sad/mad. This type of girl is very amusing but sometimes annoying, acts dumb, and has a strange mind.
Maaaan... that girl is such a chelsi
