Elevator Diffusion 

The phenomenon in which people evenly distribute themselves in an elevator, especially after people get on or off said elevator.

Failure to do so will result in very awkward situations.

John: The elevator's stopped, time for elevator diffusion!

Kate: Why is this random standing right next to me?
John: Hey buddy! Follow elevator diffusion!
Random: Sorry, man

Dilusionist

Someone who constantly lives in their own dilusional bubble. They always harp on about pulling "fitties" ALL the time; "riding ALL night long" and having great "footballing vision/skills". Realistically everyone knows a dilusionist's life is duller than an old grannies' haemorrhoid infected ass, but unfortunately they will never realise this!!

My mate told me he pulled a northern fitty at the weekend and ended up riding her all night long. What he didn't realise is that i saw the hairy munter leaving his house the next day and she said he fell asleep after spurting in his boxers......the man's a f*cking dilusionist!!
