Southbound Mud Pile 

When one defecates into a box and/or large envelope and sends it to a random southern address located in any state below West Virginia.

A40 Junction Southbound 

A rather painful attack method in which the attacker puts pressure with two fingers onto the armpit of his victim. The harder the force, the more intense the pain.

Further describing the position of the males while performing the #brooklynbridge on a female parter. Northbound lane would be plowing the female while the Southbound lane will be getting felatio from the very same woman.
