Frodo's Ring

A friend who has a tendancy to 'do a disappearing act' at inopportune moments.

"Oh surprise, surprise, Terry has fucking donned 'Frodo's Ring' again just when it's his turn to get the next round in."

"Then, just as about 20 of them came around the corner with baseball bats Terry whipped out Frodo's Ring again - the fucking cunt".
