Sounds like "nipple licker", and means pretty much the same thing. A word made up by me, and probably known by half the world by now. It also can be switched around to be "licklenipper", "lippernickle", and "lipnickler". It is a commonly used diss (in MJHS at least), meaning a person who licks nipples, even worse if the disser is referring to Ollie's nipples.

Jolene:"Oh yeah? Well you're a lipplenicker."
Breylend:"Hahah did you just call me a nipplelicker?"
