Delusionalist

Someone who uses ancient belief systems to explain the world around them. These belief systems are not grounded in reality and only serve to help the person cope with things they cannot understand. The delusionalist thinks the burden is on the evidence to reconcile itself with his delusions.

a bloke who chats up random girls but only gets as far as their phone numbers before they realise he's a complete twat and only talk to him out of sympathy.

This guy is probabally a virgin in his very late teens lying about the many girls he's bedded. yet thinks he's the hot shit!

The give away is the fact he acts like a complete virgin and will also have made up an unbelievable senario of loosing his virginity at a ridiculously young age with some one many years older!
