when you
see somebody that is fat and you want to say that they are fat without them knowing that you are
talking about how fat they are, then you use the word taf.
so while you are walking with a friend of yours and the person if front of you is
chubby.
You:
Hey, tafness at
12 o'clock
Friend: Oh yea dude, definitely taf
Taffy: I want a taffy apple too.
