A state in which a person has been annihilated by the consumption of alcohol, the amount of which is well above his/her tolerance level. Once the subject has imbibed past the limit, massive retardation sets in, resulting in the stupor. The person in this state is often referred to as a drunken moron.
A male in a drunken stupor is likely to make an ass out of himself in front of anyone around. Some activities he may participate in while in the stupor: starting fights, drunken boxing, drunk dialing, drunk texting, flirting, telling everybody he knows that he loves them, stumbling, staggering, stammering, slurring, drunken dancing, and anything else that is obnoxious and unreasonable.
That guy must have game, look at him entertain that group of hotties over there.
No, they're laughing at him, not with him; he's in a drunken stupor. Note how he can't stand up straight.
