delayed onset muscle soreness

Definition

The muscle pain and stiffness that peaks 24-72 hours after unfamiliar or intense exercise. The body's passive-aggressive way of reminding you that leg day actually happened.

Example Usage

The DOMS from my first CrossFit class made sitting on the toilet a full-contact sport for three days.

Origin

Medical terminology describing post-exercise muscle damage; became common fitness jargon in the 1980s-90s

Fun Fact

DOMS is caused by microscopic tears in muscle fibers and resulting inflammation, not lactic acid buildup as commonly believed.

It's the athletic equivalent of a quick business meeting, except with more grunting and fewer PowerPoints. Bonus points if your quarterback actually knows the play they're about to call.
