What is Rumble Packing?
1.
When a couple is having sexual intercourse while playing a game on a nintendo 64 with the support of the nintendo 64 rumble pak, during gameplay, you shove the nintendo 64 controller, (with the rumble pack attached) into the female's vagina, (while it rumbles) and then you listen to that kitty purr.
Hey justin, you wanna play some starfox 64 and do some rumble packing tonight?
