Wikipedia denotes the kip swing dance aerial as a synonym to the lamp post / an around the back.
Though this may have been correct at one time, I believe this is no longer true. I also believe this hasn't been so for a at least a decade. The kip in most communities refers to a classification of an aerial where the follower rotates completely around the right arm of the leader landing on the right side of the leader.
To differentiate the kip from the lamp post, the lamp post sends the follower in front and possibly to the right of the leader, but rarely to the left. The 'modern' kip is also commonly ended in a close position, while the lamp post is generally a flying aerial where the follower lands very much away from the leader.
Of course this could be on left side if you're doing a backwards kip, just switch left/right shoulder through this post and all the principles are the same.
The 'kip' aerial used to be just one full revolution of the follower, with the follower standing at a 90 degree angle from the leader, rotating completely around the shoulder, and landing in closed position with a tap to the ground of the right foot. Later, in the late 90's, another more difficult version became popular, the kip to the side, in which the girl did a revolution and a half, ending up on the leader's back.
Now days, because the kip to the side has become such a cornerstone aerial of performances due to it's easy ability to time to music, the term kip now is used almost interchangeably with what we used to know as the kip to the side. Rarely do I even see people doing the kip anymore without the to the side ending.
For some history, the kip inherits much fame from Lance Shermoen, who more than 20 years ago did a kip with 17 revolutions. He has always referred to that aerial as the shoulder. Since then, there have been few people go beyond the single kip or the kip to the side, perhaps only a couple of dozen couples, myself included.
Most now days who want to advance in their ability to do the kip just stick to getting a second clean and full revolution of the follower, and we call that the double -- short for the double kip. I also believe that due to the difficulty of the second rotation and the skill required to get to that second revolution, the ending of the foot tap or the double kip to the side is pretty much irrelevant. If you get that far, the ending is more related to what you are trying to put to music.
If you want a class on the kip on video, check with Paulette Brockington for the kip class I taught at ALHC last year.
And humbly, the kip is a difficult aerial. If you're getting ready to start working with it, check out this link I wrote about strength training.
