my bad!!!

I know that this is a very petty post but I just find the phrase 'my bad' so annoying-and I'm not that old!
Apparently it originated from an African American basketball player (who spoke very poor English) who said it after missing a shot. It became mainstream over there and seems to have become common over here. Alot of crap seems to come over!

The other day a painter was applying stain on our new garage door and dripped stain all over the concrete (no drop sheet!). When I looked down instead of apologising, he said 'my bad'. Hmmm...It doesn't even make grammatical sense. 'Bad' is an adjective and therefore should be describing a noun. My bad what??? Your bad bloody mistake getting stain on my new garage floor!

From the Urban Dictionary:
"A combination of an apology and a dismissal. Basically, saying "oh yeah, I did that, but I don't care".

Persons of an older generation can find this quite annoying to hear when expecting an actual apology.
"Hey, you spilled my Coke all over me!"

"Oh. My bad."

"#@%$!"

Anyway, that's my rant :)
