Many begin to defecate before masturbating, so as to start an uninterrupted fecal flow. Also, it is not a requirement to ejaculate and finish defecating at the same time, but dedicated "shankers" will attempt the 'Snow on the Mountain' technique (wherein the discharge lands on the fecal matter.)
It is not necessary to be nude, but serial "shankers" will usually derobe before attempting a long shank.
Guy 2: "Nah man, had a good shank."
Guy 1: "Well, thats me kicked out"
Guy 2: "What did you do?"
Guy 1: "My girlfriend woke up and found me shanking next to her last night."
"shank" passes usually result from a hard serve or hit, they cant be controlled, therefore they bounce off the players arms and fly out of bounds, not to be retrieved.
