Koser 

When you go to the bathroom to take a shit and instead of it being enjoyable. it feels like the world is ending if only the smell dosent take you first.

It may often splash up, as a final "fuck you" which makes the wiping process that much worse.

X:Dude I dont know what i ate last night but I just dropped a koser and am still surprised im here.

Y: Yeah man, those really can ruin not only a day but a week.
