So Joephet has been overusing the term "OA" which is a guamism, I'm told, which is supposed to be something like "over-acting," used in phrases such as, "You're so OA!"

I yelled at my kids too much today, but it was probably because I was unprepared and unsympathetic to their cross-multiplication, which I find a war-crime against true mathematical understanding when there is no intervening mathematical grounding. But I hate cross-multiplication. I loathe it so.
