A girl that is sweet, but can come off selfish. she is naive, but a slut. she is pretty, but is also insecure. she is smart, but lazy. she is a walking oxymoron.
You're a good friend but sometimes you can be a Cassie.

A Cassie is a cheating liar, that doesn’t take anyone’s feelings into consideration. Those Cassie’s will always try and make you trust them, when really they are backstabbing liars.
Guy 1: Cassie cheated on me!

Guy 2: Of course she did, her name is Cassie! They are always backstabbing, cheating liars

Anyone who is loud, irrational, and rather obnoxious. Also typically shows an eagerness for tabletop roleplaying games but despite the amount of time played and possesion of material, never gets the rules down and stoops to constantly asking the others questions.

Also an example of someone who is obscenely fat. When such a person speaks, the noise either resembles that of an irate chiuaua or a noise akin to what Cthulhu would make.

Is the type of person that people frequently don't want to spend time with but do so anyways due to a lack of resolve.
What a cassie.

That person is such a cassie.

Nobody wants to hang out with a person that acts like a cassie would.
