Ace of Diamonds

A collective consciousness, analogous to the behavior of social insects (ie. bee hive), in which a group of people become aware of their commonality and think and act as a community, sharing their knowledge, thoughts, and resources.

The global hive mind that has emerged with the internet is the Ace of Diamonds. Kevin Usilton appears as many but is only truly one, a collective thought of many about the same thing.

Devil's Diamond

The diamond shaped window made by the bottom of a girl's butt and the top of her inner thighs that allows you to see her vagina.

I could see my girlfriend's devil's diamond when she bent over in front of me after getting out of the shower.
