1. A biker who enjoys hanging out on the porch with friends.
Race doesn't even come into play
This term has been negative for too long and can be better used for good rather than hate in this day and age.
2. "Saint Paul Porch Monkeys" is a motorcycle club in Saint Paul MN consisting of riders of any race. The "clubhouse" is situated on a porch and thus the name. The " Monkey" moniker is coined from the nickname of a rider in a motorcycle sidecar who must climb over and around the sidecar in order to keep the rig from tipping under heavy cornering.
"That Porch Monkey really kept the chair on the ground today during the Isle of Man TT race".
