- This term is used to refer to a state of extreme inebriation. This word came into use through metaphoric change of the word slosh. It comes from the sloshing heard from within a stomach full of liquid. It is used exclusively in the past tense to refer following the pattern of synonyms such as ‘smashed,’ ‘wasted,’ and other words referring to a state of intoxication.
