What does lavatorial mean?
Lavatorial is an adjective meaning “relating to a lavatory or toilet,” although it is now encountered most often in figurative descriptions of crude, vulgar, or bawdy material. A lavatorial joke may concern excretion, bodily functions, or the physical body in deliberately frank terms. The word can occasionally sound like an indirect substitute for “toilet” or “vulgar,” but its use in “lavatorial humour” often carries a mildly comic or dismissive tone. It is especially useful when discussing comedy, satire, graffiti, or language that is intentionally transgressive. In careful prose, the adjective distinguishes merely toilet-related subject matter from expressions that are genuinely obscene or indecent. It appears in both British and American English, although British speakers may employ it somewhat playfully as a euphemistic label.

Lavatorial derives from Latin lavatorium, a place for washing, from lavare, “to wash.” English borrowed the related noun lavatory in the 17th century, originally for a washing place and later for a toilet. The adjective developed through the combining form “lavatori-,” with the suffix “-ial” expressing the sense “relating to.”
