A less popular form of butter face. It's a girl who you thought looked really could from a distance, but when you got up on her she looked more like a grizzly bear with tits.
"she looks good from a block or more away"
guy 1: "dude, check out that girl!"
guy 2: "hell yea. lets go talk to her"
*walks up close*
guys 1 & 2: "OMG blockormore! run!"
