2)A little known slang term for a method of female masturbation involving stimulation of the sexual organs by use of the "rumble" feature on a PS2 controller. This can be achieved through a variety of games, but most commonly Final Fantasy X, as the rumble feature is especially strong when Aeons are summoned.
Guy1-"I'ma summoning my Aeons!"
Jake-"Wow, May seems to be getting a lot of enjoyment out of Final Fantasy X!"
Bud-"But of course-She's summoning her Aeons!"
"Leave me alone mom, I'ma summoning mah aeons!"
