The nickname/moniker of professional wrestler Ric Flair, who currently performs on Raw for the WWE. Often shortened to "Naitch" (pronounced Nay-ch) by ring-announcer Jerry "the King" Lawler.
"Oh my god, it's the Nature Boy Ric Flair, the dirtiest player in the game! What's Naitch doin' out here at ringside, JR?" (obviously up to no good)
