1 definition by Major Kameltoe
n. A motorist who drives the speed limit or slower, no matter how long the line of traffic following is. This usually leads to suggestions being made by those in line as to what said motorist should be doing instead. Aggressive driving and road rage incidents occasionally accompany the experience of being "regulated" (vb.).
"Oh man, this guy is such a regulator! Why doesn't he just pull over and let those of us with somewhere to go get on with our lives?"
