The really wide guage beads (each "bead" is about the size of a baseball) that people get on Bourbon Street in New Orleans.

Knee beads...because that's what you have to do to earn them...get on your knees.
Jenny got a set of knee beads and a shot in the back of the mouth at the corner of Bourbon and Bienville.
