rave aids
The fever-ish, raspy fatigued feeling you get immediately after & sometimes days proceeding a rave. Sometimes accompanied by sore throat & cough. This affliction is obviously attributed by thousands of people (most likely with weakened immune systems due to drugs/alcohol) breathing the same air for hours & hours at a time.
*cough* *sniffle* Dude, I've had a bad case of rave aids after raging all night Friday into Saturday.
