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"..
