Eyeball Handshake - A communication between two individuals where no words are exchanged but a mutual conversation is established using eye contact. This is achieved by movement of the eyeballs in a particular pattern, followed by a significant 'head nod' to symbolize the end of the conversation between one another.
Two guys passing each other in the mall, you don't exchange words but you share eye contact and a conversation in your head, you continue walking and leave it with a head nod. This is an Eyeball Handshake.
A devise that is planted behind the eyeball, in order to capture a truly rare moment at anytime, so as to prove to everyone else that it really happened, when time does not allow the fetching of a traditional camera.
