That's Fucking Funny. For those who refuse to adopt "LOL" as a means of conveying joy and laughter via text messaging. TFF is a more appropriate response to a witty text message or photo than "LOL". The actual act of "Laughing Out Loud" rarely occurs.

Token Fat Friend

Can also be referred to as DUFF but in this instance, the token fat friend is not considered ugly. Usually considered to have "such a pretty face."

Every girl has one so they can be considered the more attractive one when going out to bars.
