couldn't find "boon skunk" but found this -
boon whore:
a once-white trashy skank that slobs on the knob of a niggy ; a monkey tester
e.g. "as we drove through town, i counted at least 7 boon whores" or "damn, this boon whore loves banana pudding" or "the manager at home depot is a straight boon whore"
