1.
Nickname of Australian superstar swimmer Ian Thorpe, the most decorated Australian athlete at the Olympics with 5 gold medals. Spelling derived from last name and definition from both his incredible speed in the pool and his trademark black bodysuit which he wears to all his competitions.
Even with the help of the Thorpedo, the Austrailian relay swim team could not defeat the US team.
