PP does this all the time so i figured itd be worthwile to write up my observations of this trick.
What is it:
Roll, and at the end, do a turnaround uptilt.
What is the theory behind it/Why does it work?:
The first is that in smash rolling is considered bad and people like punishing rolls. Falco has a pretty good roll, so this trick is meant to take advantage of the 2 facts that people like to punish rolls and that Falco has a good one.
When to do it?
Defensively only, I am quite sure. Out of a shield, or out of a corner seem to be the most useful situations, because your opponent is usually overcome by the wolf's rage and is going at you no matter where you go. This works best against characters that are all about pressure and speed, so Falco, Fox, and Falcon are standout candidates. I'm sure PP has more uses that he can share.
Why do it?
PP may have more good reasons, but for now I see 2. The first is that if someone tries to punish your roll on instinct they will probably fail. If you want to see this in action watch Jman vs Dr. PeePee, especially the second match on Yoshi's. Jman attempts to punish PeePee's rolls and gets comboed mad hard for it alot. In theory, this means that unless your rolls are really predictable, you should be able to use them to get out of sticky situations. Either your opponent keeps getting uptilted then comboed, or they just let you roll. If they let you roll, that's awesome because then you have a way out of alot of tight spots.
How to do it?
This isn't the easiest thing in the world to do, but I've found ways that make it easier. The way I do it is I roll, then during the roll I put the control stick up and barely toward the direction that my roll went, and then as soon as the roll finishes, press A. This eliminates all the hard parts of the turnaround uptilt (not jumping, not upsmashing, not turning around) and replaces just a simple direction and A that is pretty easy to get right given that you have the entirety of the roll to imput it. PP may have a better way.
It pisses people off too!
