A closet case homosexual who is uncomfortable thinking for themselves. By going to stores like A+F and spending 90 dollars on a polo or button down shirt that the manican in the front window is wearing, one defines himself as a "collar popper." Other signs include, having a small penis, working out to try and make up for it, and pencil sideburns. Furthermore, requesting 50 cent songs at clubs where girls go to dance not hook up. Also see, dueshe bag, cock boy, cum trap, or waste of oxygen
That collar popper is drinking right out of the pitcher, he must be a true gangster.
Collar poppers burn in hell when they die, but are allowed to listen to Darude - Sandstorm all day.
