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.

A British expression used to signal that a decision is final and the speaker will not entertain further argument — equivalent to 'and that's that' or 'end of discussion.' The word 'flat' here means definitive or absolute, the same sense found in 'flat refusal' or 'flat out.' Now largely dated, it was typically spoken with a dismissive, authoritative tone by someone asserting their position. You might still encounter it in older British fiction or from speakers of a certain generation.
