Jheri Curl
A popular hairstyle in the African-American community especially in the 1980's. This haircut was, as the previous entry says, a perm that loosens up the naturally tightened curls and makes the hair nice and bouncy as a result. The major downside to this hairdo was the extreme amount of maintenance it required to keep it looking pretty. Tons of hair care products made for a lot of greasy situations (no pun intended). Many jokes were actually aimed at this downside, see Coming To America (1988 film starring Eddie Murphy).
Example:
When Ricky got up off the leather sofa, his Jheri Curl left a greasy, oily stain where his head used to be. Guess how long that mess took to clean up.
