The distance of your radius that you will acknowledgethe people you know and greet them. Greeting radii almost always depend on person. Usually, your greeting radius varies based on how much you like the person. Someone you are close friends with, will probably have a greeting radius of over 50ft. For people you don't like, it would probably be something like 10ft if it's crowded where you are.
Steve: Oh dude, I had to say hi to Kent today?
Jon: Aww, you said hi to Kunt? He probably thinks you like him now.

Jon: Shit, sucks for you, haha
Steve: Yeah, GOD today was a bad day
The distance a man is able to comfortably travel (from his bed) without pants; the average radius being just the distance to the shower.
It is theorized that a man's underpants radius is inversely proportional to his confidence; that is, the farther a man travels from his bed in just his underwear, the less he believes in himself.
At first we thought it was funny; at least Marshall didn't left the house without putting pants on. But his underpants radius just kept getting larger. He started getting the paper in his underwear and even going downstairs for a drink in his underwear...!
rodimus prime is the youngest and possibly strongest prime ever. He used to be a young foolish autobot named hotrod that got optimus prime killed by megatron. after prime's death he passed the autobot matrix of leadership to ultra magnus who then lost it to galvatron. after ultra magnus was blown to peices the autobots seemed to have no chance at destroying unicron or the decepticons but hotrod led the autobots through unicrons eye and fought galvatron 1 on 1. at first galvatron was winning but rodimus beat him by taking the matrix and opening its power becoming rodimus prime, defeating, galvatron, destroying unicron, and proving that he had the touch.
