Spread of evil
Motherfucker, if you're standing in a packed train carriage and you have a cough, cover that shit up. In fact, if the train isnt packed, cover your fucking mouth. I dont like having to hold my breath for the whole journey, trying not not inhale the fucking dirty bacteria and viruses that infests in your stanky mouth, that you have kindly coughed into my direction bitch.
COVER YOUR FUCKING MOUTH WHEN YOU COUGH!!!
Or better yet, cough till you fucking die, at least there's a reason for you to cough. Not for some shitty reason like an itchy throat!
