A tool used to pound or crush something, or a person who pounds; in slang, something that is impressive or works powerfully.
From pound (to strike heavily) + -er (one who does the action). 'Pound' comes from Old English pund, related to the sound of heavy impact.
In music production, 'the pounder' refers to the bass line that creates the rhythmic force—and neuroscience shows that bass frequencies literally cause your heart to synchronize with the beat!
