Arse Hair Demon
Alternate spelling, "Arse-hair demon": An extremely small, gnome-like creature, with powers of invisibility, who sneaks up on unwary victims, and gives their perianal hair a sharp tug, causing them to shriek, and/or leap skyward, for no outwardly perceptible reason.
Ariel and Deanna were enjoying high tea with the Queen, when HRH suddenly gave a sharp yelp, and leapt from her seat. Royal Guardsmen rushed towards the table, but Her Majesty waved them off, stating, "Bugger off, ya sods, 'twas merely a wee arse hair demon, ticklin' me hindparts."
