SOYF is a term coined the voice of skateboarding and host of The HOLLYWOOD Summit Show, (Morgan "HOLLYWOOD" Monroe) and picked up by the international extreme sports community.
At the end of every HOLLYWOOD Summit Show Morgan "HOLLYWOOD" Monroe would say "Have a great day, will see you soon and "Stay Off Your Face". He later added it every departure as a goodbye. To making it shorter HOLLYWOOD used the first letters of each word making the goodbye phrase "S.O.Y.F." or "SOYF".
