O M A

A car tuner who is well overrated and thinks he's a god around a car when infact he,s just a bolt on tuner and has an ecu mapper that would probably be better at drawing ordinance survay maps!

the "O" syndrome

a feeling brought on when a current fling's attitude reminds you of an ex-girlfriend.

if your current girlfriend happens to piss you off because of her lack in a display of affection, and this fact reminds you of an ex girlfriend, then she suffers from the "O" syndrome.
