Betty needs to stop being a buskette and start combing her hair everyday, and maybe brush her teeth while she's at it.
A crummy looking person that looks trashy and doesn't have the best personal hygiene. Their teeth are normally messed up, their haircuts are abnormal, their clothing is thrift-store material, they aren't the smartest people in the world, their looks are genetically flawed, and they're people you've most likely unheard of. They're the type of people that you take a look at and say "Wow, why do you exist?" Best compared to a crackhead or dirty redneck. A hobo is a perfect example of a busket.
Sean Jenkins is the biggest busket I know. He wears that damn Dale Earnhardt JR shirt everyday with some skinny blue jeans and is in SLD classes. His face looks like it got hit with a baseball bat, got lit on fire, rubbed with sandpaper for 35 seconds, got shot at a few times, had plastic surgery done to it on numerous occasions, got stepped on by an elephant, stung by 13,463.7 bees, ran over with a lawn mower, then was dunked in some acid.
