A sex act where a girl is getting it from a guy doggy style and then another guy comes in, sits on the girls back and gets a blowjob from the guy giving it to the girl doggy style. Imagine what this looks like, and you will see where the name jenga comes from.
Jeff was on a drunken sex rampage doing a girl doggy style when suddenly Steve came into the room and tried to pull off a jenga.
