the west african fighting rabbit(cuniculus mors mortis)is an aggressive, dog-sized species of rabbit. WAFR is often used to describe someone that is short, scrawny or seemingly harmless but is, in fact, a complete hardass.
"did you see that lil guy?"
"what a fucking WAFR"
"What a fucking retard"
Andy Dick busted in West Virginia! LOL WAFR...
