The act of walking asymmetrical when your dying for a shit and are trying to make the distance to the toilet.
derived from "cotter pin" the pin that attaches your crank to your bottom bracket on your bicycle, and when worn or broken, forced your feet to pedal at different ratios.
" Tracy is rob ok? has he got a back or knee issue? he`s walking kind of odd." No he`s just Cottering, he`s dying for a shit and has to walk that way so he`ll make the distance."
