Australian slang meaning to show off, act flashy, or behave in a loud and attention-seeking way. If you're lairising, you're probably doing donuts in the car park, wearing something outrageously loud, or just being the most extra person in the room. It comes from 'lair,' which in Australian slang describes someone who's brash and showy. The verb form 'lairise' brings an energetic sense of ongoing performance — it's not just looking flash, it's actively putting on a show.

Origin: Derived from Australian slang 'lair' (a flashy, showy person, possibly from Cockney rhyming slang or 'lah-di-dah'); 'lairise' as a verb form is distinctly Australian, documented from the mid-20th century. Editorial expansion authored on Slangora (model-assisted, hedged).
