When you are continually stopped in the hall and assaulted with inane, mind-numbing factoids that a very nerdy colleague thinks are witty and intelligent. He tells them to you, to impress you, but all it does is annoy you and you feel pressured to keep saying "yeah" and fake laughing right along with him, until he is finished with you.
"Oh my god, I was just accosted in the hall by Nathan for 20 minutes with more inane facts... I do have actual work to get done today! He's such a nerd-bully!"

When someone who seems fairly mainstream blurts out something really nerdy revealing how nerdy they really are.
OMG! When Joe was talking about that book he really liked and then blurted out that, "if you look in the back of the book, it will tell you what fonts were used", he totally revealed his nerd tell!
