A smelly, loud, and rude way to show you're angry at someone for driving slow. You ride so close to their back bumper it feels like you're about to kiss their tailpipe.
My uncle did this to my mom for 20 minutes because she was driving slower than a snail.
Kailtail happened when my brother saw a stop sign and decided to speed up just to annoy me.
I got a Kailtail from a guy who thought I was going 25 mph in a 40 zone.
