Used as a suffix to a slang term, amplifies it to the upper limit (IE, grody versus "grody to the max"). Widely used in 80's slang (esp. grody to the max, from the Valley), possibly comes from pidgin.
playing mortal kombat while watching the movie mortal kombat while getting head from sonya blade after getting a check from the government for three million dollars along with a note from the government saying you never have to willfully pay taxes anymore and then having an orgasm at the same time as executing your fatality exactly when the movie mortal kombat ends would be sweet ass-tastic to the max.
