FIAFAD 

Meaning "Fall in a Fire and Die," FIAFAD is a variation on DIAF (Die in a Fire). FIAFAD is a stronger sentiment, because falling into a fire and dying is way worse than just dying in a fire.

I can't believe you drank my last Diet Coke, I hope you FIAFAD

Fiaface 

When a song or track is absolutely banging or has a dirty beat and you bring your lips upwards and outwards in recognition of such beauty

One minute we were just dancing then boom fiaface and all of sudden we were raving!
