Snooty, Intellectual Conversation

 Had the following conversation at work today:

CO-WORKER: Oh my god.
ME: What's wrong?
C-W: The Fedex guy just showed me a picture of someone's gigantic nether regions.
ME: He showed you a picture of a giant dick?
C-W: No, the other kind of nether regions.
ME: Oh. Why did he show you a picture of a giant vag?
C-W: I don't know.
ME: ...
C-W: ...
ME: So, when you say "gigantic", what are we talking about here? I mean, was it eating Tokyo?
