British colloquial euphemism for the penis, typically used with self-deprecating or lightly comedic tone. In standard usage 'old chap' is a friendly address term for a man, which makes its anatomical extension a piece of classic British double-entendre humor -- the kind that depends entirely on context and delivery. The register is humorous and slightly self-deprecating rather than coarsely vulgar or aggressive.

He mentioned the cold weather had not been kind to the old chap, which got a laugh from everyone.
Origin: Extension of 'old chap' (British friendly address for a man) applied euphemistically to male anatomy; classic British double-entendre. Editorial expansion authored on Slangora.

In British slang, old chap is a euphemism for the penis — mild, slightly comic, and thoroughly English in its preference for understatement. Old chap more commonly functions as a friendly address (steady on, old chap), and the genital meaning rides on that same tone of breezy, gentlemanly casualness. It's the kind of euphemism that makes awkward conversations slightly less awkward.

He winced and said he'd taken a football straight to the old chap.

(UK, colloquial) The penis.

For parents

"old chap" means: The penis.. The term has a sexual reference, so parents may want to know the context in which a child uses or hears it. In most cases it is part of normal teenage curiosity rather than a concrete worry. A short, non-judgemental conversation about consent, respect and online safety is usually the best response. Look at the wider pattern of behaviour, not the one word.

For ESL learners

"old chap" means: The penis.. Register: informal slang, fine in casual conversation, texting and social media but not in academic essays, business writing or formal speech. Note the regional or dialect label (UK) — 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.
