pseudologia fantastica 

A psychological condition, otherwise known as pathological or compulsive lying, in which the sufferer habitually lies. The lies are caused by an internal need to lie, not environmental or social factors. Unlike in psychotic or delusional disorders, people with this condition can recognize they are lying, though they may be unwilling to do it, leading to anger, confusion, and (in some cases) violence following confrontation.

My friend has a terrible case of pseudologia fantastica. She says she's had ten different kinds of cancers, but she's never even been inside a hospital.

I Feel Fantastic 

This is a phrase that haunts people everywhere. Children and adults alike are all terrified when they hear this. If you've looked this up, then you're either traumatized already or about to be traumatized.

When I heard someone say "I feel fantastic, hey hey hey hey," I instantly screamed and ran away.

yoga fantasies

Having sexual fantasies about colleagues in work, often more senior colleagues than you, imagining them in yoga positions. When you are least expecting it, these fantasises pop into your head when you are near them.

Tiffany: I was just sitting opposite Jamie, talking about the HPM, and all I could think about was him downward dogging me
Brad: Still getting those yoga fantasies about him then?
