ask my arse

(UK, Ireland, idiomatic, sometimes, vulgar, colloquial) , to curry favour with the powerful by obsequious flattery.

(Australia, informal) A rejection; the termination of a relationship, especially employment.

British slang meaning to mess something up, bungle it, or ruin it through incompetence or carelessness. Used as a transitive verb: you can "arse up" a plan, a project, a relationship, or just about anything that can go wrong. The phrase is mildly vulgar by British standards but is common in everyday informal British speech. Similar in meaning to "cock up" or "balls up." Delivers a tone of genuine frustration or exasperation.

British slang for the worst, most inferior, or most undesirable part of something — be it a place, an organization, a period of time, or a situation. Typically used with obvious disdain: the "arse end" of a city is the run-down outskirts; the "arse end" of a deal is the losing side of it. The phrase is direct and mildly vulgar, common in everyday British speech and far less taboo in the UK than comparable terms would be in formal American contexts.

(UK, slang, obsolete) Announced on having successfully deceived somebody.
