solo cup 

A plastic disposable cup popular for beer pong as well as for making mixed drinks, as the words SOLO on its side can help you eyeball how much of each liquid to put in. Also known as a keg cup, or simply a Solo.

red solo cup

A prominent icon in the college party culture. Once used for their value, they are now used to carry out the traditions of old days and don the imagery. Any images containing red solo cups normally invoke judgments from others, whether they be accurate or not (sometimes they only contain juice?)

Boss: I noticed this interesting picture of you with a red solo cup?
Worker: oh yeah, that was at a birthday party, we used red solo cups for juice! I promise I wasn't getting plastered or being stupid!
Boss: suuuure you were....
