Fat

Also known as "Phat", is a term used to describe deep satisfaction with something. Today the younger generations use slang like "sick" or "cool" or "off the hook" or "awesome" or "wicked"...but fat is a slightly dated term that still has a subtle charm to it. Now and then a slightly older young person will say something is fat, but middle aged people would call something "boss" or "far out"..

1."Yo son, did you see the review for that new batman game? That shit looks FAT, yo!"

2."So she swallowed too?" -"yeah, that bitch's head game is fat.."
