As in:

Don't half-ass this project or I'll fire you.

I don't want to half-ass this project or I'll be fired.

I half-assed this project and was fired.

    "Half-assed" is normally used as an adjective, not a verb. While there's no particular reason not to verb it, it seems unnecessary and unlovely to me.

  • @user1579 I ironise at the verbing of verb conccurentling an unlove for the original verbing. (Not saying you're wrong, though.) Or did you do that on purpose?

  • "Sloppy". But for for the adjective, not the verb.

There are some similar phrases such as:

  • Piss-poor
  • Half-cocked

Some good words not as deep into slang would be

  • makeshift
  • shoddy
  • unenthused, unmotivated, uninspired
  • ill-prepared
  • slack
  • lackadaisical
  • pococurante

I don't want to [be] unmotivated [on] this project or I'll be fired.

Don't slack [on] this project or I'll fire you.

I [did] shody [work on] this project and was fired.

    +1 lackadaisical, which I love, and pococurante, which I have never heard of. I'd add slack and slack-ass too.

I use "BS," which stands for "bull-sh!t." In my high school, we students often talked of BS-ing our English papers....and basically every other assignment. BS-ing something more or less means making sure everything takes the proper form (but the substance may well be ridiculous) and having neither time nor inclination to bother with it any further.

Sounds like what you're looking for. :)


I don't want to do this project half-heartedly. I want to put due effort into this project. I want this project to succeed.


I would suggest "play at":

I don't want to play at the project or I will be fired.
