Arsed

I can't be arsed.

I can’t be arsed to get out of bed today.

We asked John if he wanted to come down the pub with us, but he couldn’t be arsed.

You can keep all the macho bollocks that goes with the job. I can’t be arsed who thinks what of me to be perfectly honest and I have no time for those that are.

[…]but here’s the way you’re supposed to run it: make out like it’ll be a long, drawn out process, that you can’t be arsed and that they shouldn’t be arsed because it’ll probably end up doing fuck all except getting a copper pissed off at them.
