It’s not at all okay, but the expression comes in
handy when it is socially expedient to
give reassurance. Interchangeable with No worries.
The tornado wrecked your
house, you suffered a mild concussion and three broken ribs, the dog is missing, and you’
re on the
phone with your hysterically worried mom. “S’all good, you know, mom, s'all good. We’re all alive, praise God, that’s what counts.”
You come home to find your wife fellating your best friend, a relationship you suspected but didn’t want to confront your beloved about for fear she would get mad and
divorce you. You were always a wimp. “S’all good, s’all good,” you say as you tiptoe back out of the bedroom. “No worries. See you later, hon.”
