1. British to 'crawl', flatter or curry favour in a nauseating way. Typically used at work about a fellow employee, this is probably inspired by the now dated expressions 'arsehole-crawler' or 'arse- hole-creep'.

There he goes, arseholing again. It makes me sick.

2. Australian to throw someone out, to get rid of (an unwanted lover). The word is often used plaintively or resentfully by jilted teenagers.

I can't understand it. Robyn arseholed me last night.
