O-Blocking
When some idiot keeps calling your phone during your big moment, making you lose your focus and your climax because of their dumbass timing.
My boy got O-Blocked while trying to cum. Now he's mad and got no cumshot.
I was about to finish my meat, and my mom called. Classic O-Block.
That fool called me 10 times while I was about to blow my load. I'm still mad.
