A guy that is immediately popular. When he walks into a building e.g. a club, every girl wants to be with him, and every guy wants to be him. He can handle his drink e.g, downing a litre of vodka on a regular basis, and can go out to a club every night. He talks about himself a lot. Stuff that may appear like he's bragging as it is so unbelievable, but it is in fact modesty, as a true "radigan" can achieve much more than a normal man. A radigan is a sort of mix between Chuck Norris, Brad Pitt and Charlie Sheen.

To be successful at doing a "sandy", it requires a male to pull two female's on the same night, or simultaneously. The girl's in question must be friend's and one must be Finnish and the other Greek.
