Ginned means: Dated British slang meaning drunk, specifically heavily intoxicated. The term is a direct derivation from gin, the spirit historically associated with cheap, mass public drunkenness in 18th- and. The word is mostly archaic or historical; you will only encounter it in old texts, period drama, or school history rather than current teen conversation. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour.
