From the game "Shake it up" on Mario Party 8 for the Wii, in which a player must shake his/her can for 5 seconds and whoever has the highest stream wins. Naturally, this became a great innuendo for jerking off.
-Where the hell is John?
-Probably shaking the can.
The act of engaging in male masturbation. The pringle can represents the subjects penis, while the shaking represents the motions made by the males hand to simulate a vagina and/or anus. During the shaking process, it is expected for the male to have some type of masturbation "material" such as a pornographic DVD or perhaps a pornographic magazine. The shaking process can last anywhere from a minute to over an hour, all depending on the situation.
