Montana Mudflap
A haircut that is business in the front and party in the back. The boys in Boise call it this... We call it a Mullet; Hockey Hair in Minnesota.

Montana Mudflap
The act of taking a towel, rag, sheet or anything like that and taking a healthy dump on it. Make sure it stays on or you could smear it on. Wait for someone to walk in and unexpectadly smack them in the face with it and yell "HA Montana Mudflapped you"
So there I was waiting for Ethan to walk in and then BAM I Montana Mudflapped him in the face.
