A.k.a. The word and idea of "trill" and/or any extentions of the word "trill" (i.e. "trillest").
Why? Because you're not Bun B. Because Hell Hath No Fury came out over six years ago. Because, unless you are Bun B or Pusha, and the word "trill" is part of your regular vernacular, you are neither "true" nor "real" so much as "a dumbass."
