Phantom Shagger 

A person who tells his friends he's having sex with loads of different girls, when really he isn't getting any.

Myran is a phantom shagger. There is no way that ugly bastard is getting laid.

Phantom Shagger 

That unexplained, sudden, sharp anus pain that happens to all humans, for no reason, once a year. And you’ve to catch your breath and try to run away from your own arse.

I think I shit the wrong way or something. I got a phantom shagger just now.
