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!

O M A is overrated, overpriced and would tell you anythin just to screw you for your money and probably couldnt fix a pedal gokart!

O.M.A.R.

Out of My Age Range.

Did you see her boyfriend? He was totally O.M.A.R. She had to spoon feed him his dinner and carry his sippie cup in her purse.

Did you see his girlfriend? She had velcro-strapped shoes and looked like she should have been pushing a walker. She was totally O.M.A.R.
