A unit of measurement. It is the number of dicks thathave been in a woman's pussy,sucked or taken in the ass by a queer etc. that if they were laid end to end would stretch one mile. That is all the dick theyhave had is measured in dick miles.
Where some guys are waiting there turn at the urinal and a guy behind another because he gets pissed off and/or just for fun pisses on the ass of the guy in front of him. There he will probably have to run.
