that generic-looking, often red, plastic party cup you see at generic parties.
I heard that Buzz only drinks out of generic party cups. I like generic party cups because they're often red. Why do you like generic party cups?

Similar to 'Thats what she said' but more sophisticated grown up, party slang. Used especially when alcoholic beverages are involved and they are disguised in red party cups.

Get the In A Red Party Cup mug.
The plastic SOLO brand cup you drink whatever the hell it is you're drinking now, you can't remember, at parties.

People buy them for everything becuase they're cheap, and no one cares that the'll all end up in land fills.

Usualy red, but sometimes blue. They're flimsy, amd crack easily. Especialy if you sit on one.

If you're not sure if it's yours, please don't drink out of it. You could get mono.
Fill a generic party cup with urine, and set it on that asshole's ceiling fan.

Now run.
