After you have been broing out and hooking up with chicks for the past week you end up with you think is a simple cold. This is no normal cold however, in fact after you lose the sore throat and drainage associated with normal colds. You gain the dreaded slut flu cough. This cough cant be fixed with medicine; the only way is to get hammered and temporarily fix the cough until it runs its course. This cough can last up to five months and normal occurances last a few weeks to a month.
"Stazz you have been coughing like a smoker for a week are you sick?"
"Nah bro I think I caught the slut flu after the makeout sesh with that rando chick, lets go out and drink so I can shake this."
