Why 84 you might ask? It's a cryptic/ Acronym for "The Hemmy." If you go onto your dial pad on your phone and look where the 8 & 4 is located at, the letter "T" appears where the 8 is at, the letter "H" appears where the 4 is at. Therefore TH = 84. 84 stands for The Hemmy which represents US including YOU.
