Tiggler
A vibrating barbell made for tongue piercings for the obvious purpose of enhancing female stimulation during oral sex. Originally only available in stainless steel, they now come with rubber "koosh" balls.
Ever since I got a tiggler my girlfriend wants me to eat her out ALL the time. Not that I mind.
Dick Tiggler
