Half-ass

the only abortion she could get even in the city would be a half-ass job by some half-ass doctor who could mess her up for the rest of her life

Now, we go out there and we half-ass it because we're scared, all we're left with is an excuse. We're always gonna wonder. But, we go out there and we give it absolutely everything… that's heroic.

if you're working for me and I send you to do a job and you half-ass it, that reflects on me. In civilian life, we'd just fire you. Here I can't get rid of you.
