Truckold

Portmanteau of truck + cuckold
A needlessly aggressive and inconsiderate driver of a pickup truck, often a recent model crew cab short bed, with a tendency to behave as though they own the road. The vehicles may be stock or modified, with drivers of different backgrounds, but the behavior is the common thread. Common truckold activities include:
- Tailgating (bonus points of the driver in front is already going well above the speed limit)
- Cutting off other drivers
- Installation and use of LED light bars and/or standard high beams with the intent to blind other drivers
- Speeding up to block a pass on a two lane road
- Aggressive behavior towards pedestrians and bicyclists
- Tendency to initiate or exacerbate road rage incidents
Similar to brodozers and has a considerable overlap, but refers to the drivers rather than the trucks themselves.

When a guy buys a new truck, then his wife gets the truck in a divorce, then a a few months later he sees the ex-wife's new boyfriend driving the truck the guy bought when they were married.

When you're trying to pass on a two lane road but can't because they are two trucks side by side going the same speed blocking you.
