had to look this one up 
I guess “shave and a haircut” is dying out as an anglophone meme anyway. people my age and younger have to be taught what a “bit” is, anyway. But cursing some jerk who cuts you off and their mother in the most severe way? that’s a meme with staying power. What with the hispanic population ceasing to be a minority in the US, I’m predicting the meaning will flip for the whole culture in short order.
