|1.||idiot tax rebate|
An unexpected windfall that makes you feel really excited and happy - as long as you don't think about how much idiot tax you paid in the first place.
Me: Hooray! Hoorah! I've won ten quid on the lottery!
Wife: Yeah, but you buy two tickets a week, so over the last year you've wasted over a hundred quid. This is just an idiot tax rebate.
