“Stop Stabbing Your Brother!!” “Whatever”
OK, I got it from Barry Ritholtz’s blog — not my 10 year-old son (who started saying “whatever” at age 5: Examples: “Go to your room!” “Whatever.” “Stop stabbing your brother!!” “Whatever.”)
So what is it?
“YMMV” — as in, “your mileage may vary.”
Use as appropriate — YMMV.
P.S.: are all kids now precociously sardonic, or just mine?
