C.O.D. Blocker

Noun, pronounced "Cod" blocker

Any person or thing that keeps you or someone else from playing countless hours of Call of Duty online.

Example:

T: Dude, you said you were going to get online and play some Call of Duty with me! These insurgents are going to kill themselves. What's the deal?

K: Sorry dude, I was, really. It's just my girl-friend, she's all "you need to spend some time with me." and crap. I just can't do it right now.

T: What?! She's being like that? Dude she's a total C.O.D. blocker!
