I can do that but I don't wanna - A dumb way of saying you're too good for something but you'r

A dumb way of saying you're too good for something but you're not actually going to do it. It's like bragging but not following through.

'I can do that but I don't wanna' when your teacher says you can skip the test but you're still going to fail it.

'I can do that but I don't wanna' when your mom says you can clean your room but you still throw your socks at her.

'I can do that but I don't wanna' after seeing your cousin run a marathon and you're just too tired to walk to the store.
