Not quite a double date, but not exactly a date either. It's when you invite someone out on a date, and they pull a defensive maneuver and bring a friend along, as a date shield.
Dude, I asked out that hot chick Sally on a date Saturday to cool party. She said yes, because she knew it was a cool scene, but she turned it into a one-and-a-half date, bringing along her BFF Tina to cock block.
Similar to a twenty-one gun salute, but with cocks. Used as a mark of respect for absent friends, or to toast the end of a particularly enjoyable social occasion. The trousers may be dropped or the penis merely flopped out; it is the saluter's choice. Penises are held upward, like a cannon, while a moment of silence is observed.
N.B. It is considered extremely bad form for the penis to be anything other than completely flaccid when performing a one cock salute.
Let's give her a big one cock salute. It's what Kewley would have wanted. (If, for example, Kewley was the friend who was unable to attend).
Our antics in the ball pool deserve a big one cock salute.
