Used when two gay guys have sex doggy style. The "top" guy gives the "bottom" guy pleasure by reaching round and masturbating the penis. Can be used by non gays to describe someone who has not done something that you would expect them to do due to "common courtesy".

Also, if someone is a tight arse.
Dan "That dude did not hold the door open for me"

Mike "Yeah - I bet he doesn't do the common courtesy reach around either"
