There are literally dozens of words for being drunk or a drunken person and they span the spectrum from the harmless to the bad, from the words you can (almost) use in polite conversation to slang expressions best left to frat parties.
Here are some common ones:
Blasted – definitely not an appropriate word when talking to your boss
Hammered – sort of like blasted so also better used at a prty among friends then the company Christmas function
Intoxicated – the official term, sounds very “official” like something a doctor would say
Loaded – like hammered or blasted but also means to have a lot of money – ‘see the guy over there, he is loaded, owns half of the city.”
Pickled – like hammered
Pissed and shit-faced – really bad vulgar slang, frat house use only
Spaced – spaced out, refers more to being high on drugs than being drunk
Tipsy – being slightly drunk like after one glass champagne too many – mild expression and not appropriate for someone really drunk
Under the influence – official expression, used by police and lawyers, also found in the acronym DUI – driving under the influence
Enough talk about drinking, I am going to get a drink now!
