Spoony Dave
When someone reaches a non sober state and starts acting in a bizarre and odd fashion. Their facial expressions are in some way retarded and their communicative skills have deteriorated beyond recognition. They are normally smart, friendly people who let out their spastic personality hidden within.
Someone is wearing a vampire mask making weird and animal like noises for no particular reason.
One of his friends will then comment saying "look its Spoony Dave."
