Receiving filatio (blow job) from a sista, in the back of your jeep with a gun pointed at her head. Vomiting may or may not occur, but afterwards the hair on your scrotum becomes nappy and obtains the qualities of the African Wilderness.
"I have a problem, it's my balls; they're all nappy."
"Man, you've been dipping your wick with the sistas. You must have caught the safari balls"
on my peepee."
