Dylan's Theory of Faggotry- this is an abbreviation for the algebraic expression to measure how gay your friends are.

Expression: Fag shit squared+Fag Actions/the term fag cubed= Faggotry Level

The higher the Faggotry Level, the more gay you are.

Designated Texting Friend

That one person that always tries to text you, but you lightly brush them off, until you are out socializing with people and their phones are constantly being blown up, then you text that person or your DTF so nobody suspects you are an inadequate socialite.
