Uh, sick...Well, I've been waiting for this moment >:)
So, this coworker likes big...you know. Maybe she's referring to you as a person, not just a part of you. If she'd asked me a month ago, I would have told her you're a big one, but don't worry, she likes you for it. I guess your username is more fitting than we thought.
Was that ruthless enough? Don't judge all of us based on me because I simply could not pass up this sort of comeback. I'll be cleaner from now on :)
