Any man who drives around all day on a Harley or in a sueped up truck that is lifted enough to look like a monster truck. Often times they will sit in a driveway and rev there engines at 2:00am when everyone else is trying to sleep. One thing that is very important is the vehicle needs to be obnoxiously loud. Doing these super masculine things makes up for there small dick.
Extreme cases include things such as testicles hanging on a trucks trailer hitch or handle bars on a motorcycle that reach 3 feet in the air (making it extremely hard to drive, yet extremely masculine). These extreme cases fall in the subcategory of baby dick bastards (or BDB for short). A BDB's dick is extremely small, much like a baby carrot.
Jim was woken up at 3am by a little dick bastard reving his motorcycle up in the middle of the night.
