To clobber means to hit someone or something very hard, or to defeat an opponent completely and overwhelmingly. If a baseball player clobbers the ball, they smash it with tremendous force, sending it sailing over the outfield fence. If one team clobbers another in a basketball game with a final score of 95 to 42, they've won by such a huge margin that it wasn't even close.

The word carries a sense of total domination or powerful impact. You might say a storm clobbered your town if it caused serious damage, or that you got clobbered by a difficult math test that caught you completely unprepared. In British English, clobber can also mean clothes or equipment, though this meaning is less common in American English.

When you hear clobber, think of something decisive and forceful: winning by a huge margin, or hitting something with real power. The word has a satisfying, emphatic sound that matches what it describes.

As a noun, clobber can mean clothes or personal gear, especially in British English.
