No duff means: An incident that is not a drill or training exercise; an emergency. Also end of exercise. Stop drill immediately. As a ‘tap out' called by during physical training. Sim munitions training in. It is military jargon and mostly appears in service contexts, war fiction, or among veterans and their families.

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.
