What expression falls out of your mouth when you hurt yourself? If proof were needed of how deeply ingrained our upbringing is on us, here's an example:
I burn my hand on the cooker and reflexively shout:
'Einau blixem Maria Fuck'
Thanks to my mongrel heritage. (Anyone who can guess where my forebears hailed from wins a gold star.)
Now I'm curious as to other people's personal verbal knee jerks. What have you got?
