Unbacked underwear that allow you to visibly see ones butt while wearing nothing else. AKA. a thong.

stands for uneccessary boyfriend usage. when girls say the word boyfriend as much as possible so that it becomes perfectly clear that they are loved. used primarily by girls with low self confidence.
Marissa: so i was talking to my boyfriend today, and he was like "god marissa being your boyfriend is so neat" and i was like "yeah having a boyfriend is the greatest."
Bonnie: geez marissa, keep the ubu under control.

An unwiped asshole.
It sucks having to drive to the store with an ubu because you ran out of toilet paper unexpectedly.
