1) Literally, one who fucks skulls.

2) In more recent usage, lame ass trendsters who have hopped on the latest trend of wearing clothing with skull and skeleton motifs. They range from the 98 pound emo dude who sits behind you in math class, to "hip-pop" superstars like Diddy and Souja Boy. What they all have in common is un-originality. Skull and skeleton motifs on clothing were originally a staple of skater/hardcore/punk circles, and even gangsta rap as evidenced by Ice Cube in his classic 1992 video "Wicked". But then the "Pirates of the Carribbean" movies came out and suddenly "skulls were cool" and everyone and their momma were wearing clothing with skulls and skeletons on them. The truth is they are all part of the sheepherd jumping on a trend and only show how mindless and unoriginal they are. When you see R&B boytoys, hip-poppers, 14 year old girls, scenesters, wannabe pirates, bros, and rebel wannabes, etc. all following the same trend, you know this fad is just about over.
1) Watch out for that skullfucker or you'll wake up missing an eyeball.

2) Billy though he was hip and trendy in his skeleton ribcage hooded sweatshirt, but all he proved was that he was just another mindless skullfucker with no originality.
