@TruthSandwich @freemo @wdlindsy Same here, although at my age I no longer hesitate to question the usage. I know how easily these things can become deeply engrained unthinking habit. There's one I've had since I was a teen that STILL comes to mind and I have to catch it. It really pisses me off. I won't repeat it here.

Some of them originated in the elementary school / junior high crowd, such as "that's gay" as a negative expression. Fortunately, that one seems to have disappeared from language over the years.
