Slutty girlfriend pees in a cup

I have returned home after a fun night and tell you how much fun I have had but you become jealous. Okay, I know that I kissed 4 people tonight, perhaps done even more than that but didn't you want me to have fun? I try to seduce you, but you seem to be too mad about me getting with other people. After finishing a glass of water I'm about to go to the bathroom when you say that it's not working. Has our annoying flatmate broken it again? What am I supposed to do now? I can't just go to pee out on the street! Well, I guess there is just one option. I take the empty glass and pee in it.
