Kailtail
When you drive right up someone’s back bumper like you're trying to make them cry. It’s called Kailtail because it was named after a guy named Kail who had no idea what patience was.
I got a Kailtail from my brother because he saw me driving slower than a sloth.
My friend did a Kailtail to me because I took too long to stop at a red light.
The guy behind me did a Kailtail so close I could see the back of his head in my mirror.
