Input: Text: so today i was hanging out at my friends apartment. my friend was in the shower, and only has one bathroom in her apartment and i really had to pee, so i peed in my mcdonalds cup and poured it down the sink. i figured it wasnt that bad seeing as the only other person in the apartment was in the shower and the door was locked.

i left my empty pee cup on the counter and went to my car to get my phone i had left in the glove compartment. when i came back my friend was sipping on a tall rum and coke- straight from my empty piss cup. 

i didnt say a word and let her re use the cup like 4 times before throwing it away

TIFU by letting my friend drink from my empty piss cup
