cassy is a girl who is most likely very self centered. lovely name, but she sucks. pick me; thinks everyone is talking about her. usually brags about herself, when she doesn’t have it. (large chest, a boy friend, friends etc.) if she does have a boyfriend his name is usually Thomas, Link, Eric, Bart, or sam

Either the life of the party or the buzz kill of the night. A bit emotionally manipulative, but is super cute while doing it. Lives up to the name Cassandra, the prophet who no one believed since everyone tries to gaslight them.
Did you see Cassie last night? She was so grouchy then 11:53 PM came and she was killing it in beer pong

Get the Cassiemug. The most annoyingly terrible person ever. It is just so easy to hate them because they are always so shitty and rude. They're the type of person to trip little kids for the fun of it and just walk away.
Person 1: I can't stand Cassie today, she's just such a bitch.
Person 2: I know! Yesterday she tripped my little cousin for no reason and he hit his face on the dresser!
