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.
