Fukushima Release Valve 

The progression of the Japanese Blindfold where the groom proceeds to go further down the bride's face, and his anus envelops her nose as well, then farts spewing toxic gas out of her mouth and into the air. Results in a subsequent Howl at the Moon, and possibly what can only be known as The Hiroshima.

Note: While hilarious, this is not a recommended progression of the custom since it has resulted in pink eye and bacterial pneumonia.

I can't believe he pulled off the Fukushima Release Valve! What a lucky biride.

Valve can't count to three 

The fact that Valve (Game creators) can't count to three but can to 4,5,6 etc. popularized by the fact that the third Half-Life game wasn't Half-Life 3 but Half-Life 2:Episode 1

John:Hey! Can't wait till Portal 3 comes out!
Jack:Umm... Valve can't count to three, idiot.
John: Oh! Then let's wait for Portal 2: The Sequel.
