A smart move made by a marketer in order to associate the wii with normal everyday teen life.

To make such a word, you first have to take something which relates to teens, say... you use the word "reflexes" for instance. Then you take said word and redefine it into "wii-flexes" and of course you write something positive about the word aswell like "Ungodly reflexes possessed by a wii-player" and there you go!

Now you have a new and kewl word which is likely to be picked up for a bit by all the players of the wii console and redistributed since it's now a fad. Also, you now also have a free advertising channel in the urbandictionary aswell.

A Wii gamer's virtual penis size based on his or her feats and accomplishments on the Nintendo Wii.

A player's wiinis size can also be carried over from gamecubenis, sixty-fournis, snesnis, and nesnis sizes.

Also, anyone with a wiinis scoffs at anyone with a P.S.threenis or a three-sixtenis.
