"buck down" means: To defeat (someone) in a challenge; to beat up or destroy (someone).. It carries a violent or aggressive reference, so it is worth noting the context.

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.
