One who tends to cockblock others around him in a consistent manner. Much as a clock will never fail to tick, such does this person never fail to cockblock.
Man : Hey, want to go to my house and watch a movie or something?
Girl: Umm, yeah sure let's go righ-
Clockblocker: Yo you baggin it up?
Man: Yo stop being such a clockblocker.

A person at the workplace that is taking too long at the punch clock, and blocks you from punching in on time.
Damn, I would have been on time, but Julio, had me blocked at the punch clock. That clock blocker!
