Ass negative 

At the end of any online competitive game mode where you or any player goes negative in K/D and loses the game mode.

That recon player went ass negative with his 1-7 K/D.
No wonder we lost, half the team went ass negative and didn't even PTO.
Lost all my subs cause I'm always ass negative on my COD stream.
We dont accept ass negative players in our clan, by a scrub.
