cockblocking keyboard 

The keyboard that was shown at the beginning of the 'Hell To The No' number in Season 2, Episode 16 of Glee. It is the 'cockblocking keyboard' because the scene before 'Hell To The No' was the scene of Kurt and Blaine's first kiss. Right before they were about to show Kurt and Blaine's steamy second kiss, the scene cut to the angle of this keyboard, thus instigating a cockblock among the Klaine fandom.

Person 1: What's so special about this keyboard?
Klaine shipper: It is the cockblocking keyboard of evil. I WANT MY SECOND KLAINE KISS!

Self-cockblocking 

The act of being so stupid that you always ruin every single chance you get at getting laid

Guy1: That guy sucks at getting girls.... Guy2: If only he'd stop self-cockblocking, then just maybe he'd lose his virginity.

cockblocking roommate

Somebody who never leaves the room whenever you could fulfill your sexlife. This kind of people disrespect your privacy needs either because they don't give a fuck about you or just simply being an asshole.

"Dude I picked up that hot chick yesterday but I couldn't bang her "
"How comes? "
"'Cause my prick cockblocking roommate were staying in the room all time again, it was the 3rd time he ruined my sexlife "
