British slang for an erection. Typically used in casual, humorous contexts rather than genuinely explicit ones — it's the kind of term that gets a laugh in a sitcom or a lad-mag article rather than anything more serious. The word 'lob' carries a sense of something loose and somewhat accidental, adding to the comedic flavor. Common in British comedy writing and informal male conversation.

(UK, slang) An erection; an erect penis.
"lob-on" is sexual slang. In short, it refers to an erection; an erect penis. Among teens it is usually used jokingly, as crude banter, or in TikTok-style algospeak rather than as a serious statement of behaviour. Persistent or aggressive use directed at a specific person, especially online, is the bit worth paying attention to: that can shade into harassment. If you hear it once in a chat with friends, it is probably nothing. Repeated targeted use deserves a conversation about respect.
"lob-on" is informal English meaning an erection; an erect penis. It is mainly heard in British English (and Irish English). A more formal or neutral equivalent would be something like "an erection" expressed in standard vocabulary. A common mistake is to assume "lob-on" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.

- boober65%
Informal, somewhat playful slang for a woman's breast, almost always used in the plural — 'boobers'. Sits in the same register as 'boobs' but with a slightly goofier, more affectionate quality. It's the kind of word teenagers use when trying to be funny, or adults deploy in self-deprecating humor. Not particularly offensive in casual contexts, though obviously inappropriate in professional settings. The '-er' suffix adds a mild comedic energy that takes the edge off what might otherwise feel crude.
- baloney pony64%
A humorous, rhyming slang term for the penis. Primarily used in crude jokes and comedic contexts rather than as a genuine descriptor. The term is part of a long tradition of playful, food-based or animal-based euphemisms for male genitalia in American and British English. The rhyming quality makes it feel more like a punchline than a slur, giving it a lighter register than many comparable vulgar terms. Most at home in lowbrow comedy.
- custard cannon64%
A comedic British slang term for the penis, relying on the absurdist imagery of combining a dessert topping with military hardware. This is firmly in the tradition of silly, juvenile British euphemisms that achieve their effect through sheer ridiculousness rather than aggression. It's the kind of phrase that turns up in schoolyard banter, crude comedy, and any context where someone prefers a laugh over a clinical term.
- boy in the boat63%
A playful, euphemistic slang term for the clitoris, drawing on the visual metaphor of a small figure nestled within a surrounding structure. The phrase has been in circulation in English-language slang for well over a century and sits in the tradition of whimsical anatomical nicknames. It's more old-fashioned than clinical, carrying a winking, knowing humor. The term surfaces in sexual health conversations, comedy, and literary references to informal bodily vocabulary.
