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!
