Someone who has an overwhelming fear of women wearing traditional Islamic dress i.e a burkha. This phobia usually stems from childhood, as burkha clad women look like the ghosts from pacman.
Tracy: "Stevey baby, I thought I'd wear something special for you tonight."
(Tracy enters bedroom)
Stevey: "GET AWAY FROM ME YOU SHEET WEARING SPAWN OF SATAN!!!"
(Stevey recoils in terror and bludgeons himself to death with the bedside table. He was clearly a burkhaphobe.)
