A Boris 

Imagine you want to live in Dave's house. To get it, you walk in and openly do a massive shit in his front room. Dave moves out. Thing is, your shit smells so bad you decide you don't want it after all. Leaving the house, and the rest of the street for that matter, a desolate rancid mess.

This is known as doing 'a Boris'.

'Did your mate end up with that bird?'
'Nah, he totally Boris'd it. Prick.'

'Are you going to take that job?'
'Maybe'
'Just don't do a boris, yeah?'

A Boris 

Someone who is really bloody useless or a liar and generally a waste of space.

He is ‘a Boris’. He lives with his Mum but tells everyone he has a big house and he can’t even tie his shoe laces, and he is 54!

Pulling a Boris 

It means taking someone elses crush. An asshole who goes after his friend's crush and dates her even though he has dibs on her first. Being a total douche bag or dick head.

Dude Josh stop being such an asshole! Stop pulling a Boris! Edward had dibs on her first!
