look up any word, like blumpkin:
a nail that splits or separates, catching on anything/everything ESPECIALLY POLYESTER!! if you aren't close to a nail clipper, this 'barb' will torture you for all eternity until you can 'chaw' it off; or find some kind of tool that will 'fix' it up!
me gonna sucker-punch this nail barb!!

this nail barb is about pissing me off!

this nail barb caught-on and ripped a hole in my vag-hair sweater!
