Driver who, when entering the freeway, attempts to
pass every car possible via the on-ramp before merging as the on-ramp
ends (despite having numerous opportunities to merge safely prior). Of course, if oneself is doing it you're an on-ramp
hero. If someone else is doing it, they're simply an asshole.
Passenger in my car: "Dude! On-ramp
hero. You can pass a least
six more cars."
Some jerk trying to play on-ramp
hero nearly caused a wreck on my way to work.
