Stank ass breath
It whenever a nigga decides to not brush his teeth for a few days, so he starts to develop a thing called "ass breath". Days later it develops into a thing called "stank ass breath". The nigga ask you does his breath stink, you do not reply, but find the nearest computer and type in stank ass breath. If the nigga is still there I think that he gets the Idea that they have stank ass breath. If they are still breathing on your neck, you should tell them out loud, "NIGGA YOU GOT STANK ASS BREATH!" Hopefully the nigga will feel bad and brush his teeth.
Nigga who has not brushed his teeth in a while and ate cheese. Stank ass breath.
