(British, Irish) Bad luck, failure, or evil befalling.

...and so says the king to himself, "the divil receave the dhrop of that wine they shall get," says he, "... bad cess to the dhrop," says he, "my big-bellied bishop, to nourish your jolly red nose..."
Origin: . Occurs in print at least as early as 1831, when Samuel Lover used the expression as one already long-established. He unambiguously stated the derivation of cess in the malediction bad cess to be an abbreviation of success. OED speculated that it either was from success or from assessment meaning a military or governmental exaction. Origin information sourced from Wiktionary contributors (CC BY-SA 4.0).
For parents

"bad cess" means: Bad luck, failure, or evil befalling.. This is a fairly neutral word with no inherent risk attached. There is no real cause for parental concern; it is descriptive vocabulary rather than something dangerous. If your child uses it, context will usually make the meaning clear. A brief, curious question about where they heard it is generally enough to know whether to follow up.

For ESL learners

"bad cess" means: Bad luck, failure, or evil befalling.. Register: neutral, standard English, usable in most everyday contexts. Note the regional or dialect label (British) — usage may sound odd outside that variety. 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.

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.
