Sakashita, end thread. http://boxrec.com/boxer/504634 His parents had an inkling when they named him he'd be mediorce, Yusuke has 8 losses.
Yusuke Sakashita is definitely the worst name I've heard of for a boxer, and I'm literally lol. But to be pedantic: his name of course for Japanese wouldn't have the connotation it does for English speakers. And most of ya guys aren't following the topic: it's last name, and most appropriate for a boxer. Fury has to be up there. Come on, if your name's Tyson Fury, you're a born fighter. And Dick Tiger. Khaiosai Galaxy and Kid Chocolate sound pretty cool, though I don't know if that was either of their actual surnames.
We have a winner. "And introducing, the IBU, IBC, HBO, WD40 Champion of the World it'sssssssssssssssssss YOU SUCK SACK O' SHITaaaaaaaaaaaaa......"
