If someone finds a random person on Facebook and clicks on a random friend, then clicks on that random person's random friend and so on and so forth, then the original person (the clicker) will eventually circle back until they find someone with a "mutual friend."
Bob sees Sally's profile. In Sally's profile, Bob click's on Terry's friend icon. After being rerouted to Terry's profile, Bob clicks on Jerry's friend icon...etc...until Bob finds a mutual friend. This is due to the "theorem of facebook circularity."

The pleasure one obtains when one farts while passing through revolving doors, and then watching for that moment when other people pass through the same doors, smell the captured fart in the compartment, and react to the gift that keeps on giving. Similar to Linear Fart Fetish, when one farts at the bottom of an escalator and then turns around to watch people below as they pass through the invisible cloud of odor.
Wilfred could entertain himself for hours, indulging his circular fart fetish, by passing gas in the revolving doors at work, then watching from the sidewalk as his co-workers got caught in an endless cycle of his noxious contributions.

Sometimes done without knowledge of the participating parties but is actually a tactic used by two or more office employees trying to cover each others ass while also avoiding workloads while they are both out of the office. Working like a circular reference error, it is when two or more workers set up their out of office message referring another contact person in the event of any urgent or pressing matters ... only to taken when in fact they reach out to the other contact to find out he or she is also out of the office and is referring the orginal sender back to the original request

Derived from the more common act of the Man-Train, very similar in its nature though it solves all issues you may have come across with the engine and caboose missing out on the full experiance.

To engage in a circular Man-Train you simply form the train but instead of forming a straight line you slowly stand on a 25 degree angle untill all parties are forming a circle thus closing the gap and creating the Circle. Be sure to stretch
