if you go down on a chick who smells like she's just been to the gym (then you're an idiot), and your throat starts to feel like it's closing up, you might have just gotten chlamydia. congratulations!
the good news is, like every other "std" in affluent white communities, this is cured with just a couple pills from kindly doctor so-and-so. maybe next time you'll have the fortitude to smack that bitch and tell her to shower...and if she still smells like tuna and rusted metal, call off the troops.
