As in sending one to someone through the post anonymously.
No, I'm not going to do it IRL. However there is an ex of mine who is a complete asshole. And made my life an absolute misery for a good few years.
Having a bit of a Facebook trip down memory lane and I clicked on his profile. To find that he has a picture of himself outside his new house. With a plaque on the wall 'dickhead towers, nobhouse estate'. Nobhouse estate being the new exclusive housing estate that's popped up the other side of the city.
A glitter cannon would be an oh so satisfying addition to his new house. And because he's the sort of person who could start a fight in an empty room there are a lot of people he has pissed off in his time so he wouldnt get it was me either.
