hammer up
Slang meaning to physically beat up, harm, or decisively defeat someone.
Definitions
Slang meaning to physically beat up, harm, or decisively defeat someone. The term draws on 'hammer' as a verb meaning to hit repeatedly and hard, with 'up' as an intensifier suggesting thoroughness and completion. It is used in both literal (physical fight) and metaphorical (competitive defeat) contexts, sitting in a register of informal, direct, slightly aggressive speech. The 'up' signals finality -- the job is done.
They warned him that if he showed up again, he'd get hammered up proper.
Comments
Slang for beating someone up, delivering a serious defeat, or physically or metaphorically destroying an opponent. To hammer someone up is to go beyond a simple win — it implies dominance, force, and leaving them worse for wear. Used in fighting contexts but also extended to sport, competition, or any situation where someone gets thoroughly outclassed and roughed up.
They warned him not to start trouble at the club, but he didn't listen and got hammered up outside.
