"So i went into the restroom right after Josh had dropped this rank ass turd, then when i was washing my hands after pissing someone else came in and thought i was the one who stunk the place up. Josh totally wrong numbered me"
When you give someone a false number so that you don't actually have to speak to them again. Normally after you've met with someone new, and being the polite person that you are, don't want to say no to exchanging numbers. That way they think you are a nice guy, plus you don't have to explain to them why you don't like them. If the cover is blown, the person who got wrong-numbered can be blamed for not taking down the number correctly.
