I rarely partake in internet arguing and I really don't like keeping threads like these alive, but boy you sure did get to me when you called my mom a whore
Let's start out with the basics, a lincoln loop is a sideflip. Granted, there are 360 degrees of rotation in a lincoln loop, but you don't call it a "lincoln 360". Just like you don't call a backflip a "backflip 360".
Now you go ahead and try to land a "lincoln 720" but depending on how you think you're doing a "lincoln 720", you will most likely be doing a rodeo 7, a cork 7, or a misty 7.
I have posted a video below to help you getting started. If the guy in this video spun a little more at the end, he would've completed a lincoln 360 I guess. So now, you just need to replicate that guy and tack on an extra 360 while you're upright at the end of the trick. That seems very challenging, and I don't know of anyone that has ever successfully completed that rotation, but hey you seem like a positive guy with the right-can-do attitude that can easily land the first one.
