Someone who's living it up at the taxpayers expense. A passenger on the gravy train.
After feeding at the trough, the political gravy swiller raised a toast to all the poor people that couldn't afford to be there.
A swiller; someone who swills water over your welly tops. Or to jettison water down a pothole onto a fellow caver to great jubilation.
That swiller swilled me!?! By-jove I have been swilled!
Name given to someone usually of young age who walks around with a Costa Coffee / Starbucks cup being gestured in a circular motion, hinting either a cold beverage that used to be hot or being a basic brand bitch.
Got stuck behind one of those bloody swillers in the coffee shop this morning, ended up getting a iced smoothie in his insulated mug!
