1.
a group of individuals (usually in high school, though it can be a lifelong classification) who "party" with plastic red cups (hence the name), but really, no one else cares what they do and they have no social bearing outside their group.
"I heard those kids got drunk this weekend."
"Who cares? They're red cups."
