"knockdown" means: An act of knocking down or the condition of being knocked down.. Register: neutral, standard English, usable in most everyday contexts. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.
“I’m in a 3am fight with my body. Knockdown, dragged out, digestive brawl. The rumbles in the tumbles. Final analysis of the combat from the judges? Full ten rounds. TKO. This meat puppet got hands, and it fights dirty.”

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
