a driver who, for whatever reason, insists on having both hands on the steering wheel for dear life at all times, as if they were either still taking the damn driving test, or the wheel requires so much strength to move that they actually need both their arms to steer.
commonly seen among immigrants, the elderly, overweight and/or bespectacled soccer moms (in most cases while driving their infuriating "ninny vans"), and gay men.
"I wish those fucking grippers would learn how to drive properly, they can't seem to understand the road signs or know when to make a lane change.....but God FORBID they drive without both hands on the damn wheel!!!"
An old person.
They tend to grip on to things like zimmer frames, or boy scouts. Can be used as an insult towards people who are actually youngish but tend to do old things like eating worthers originals.
