Harder than funk, funkier than metal, sexier than funk metal.
More of a description of individual songs than a real genre, but may extend to entire albums and some artists could even be described as such.
Usually the result of a harder funk metal band bringing in a (possibly female) guest vocalist from another genre...with sexy results.
-Yo, did ya hear dat song Primus did wit' Tricky's vocalist Martina?
-Yeah, I never thought a Primus song could be sexy. It's like "erotic death funk".
