This is a known technique, you can use it in different ways and it's useful too, since many people forget that when you usually airdodge, performing side B will stop your momentum and help you survive.
I literally spam (or mash?) side B every time I get launched far. That said, I live until crazy percents to the point where my friends and my opponents get annoyed. (often become the stock warehouse when playing teams)
It's a helpful technique and if you do it,
move your control stick towards the stage so you don't accidentally SD, you are really close to the blastzone.
Other times, it has happened that I was launched too far and, even though I spammed side b the whole time, The side B still fired, but I still got KO'd because I didn't get out of hitstun as early.
The drawback is that you lose a great tool for recovery. You can mix up your recovery by Rocket stalling in the air and landing or doing something else. This however can be solved by spamming side B TOWARDS the blastzone. This way, the rocket will disappear immediately.
Even then, You will be facing backwards and you will have to move your stick backwards towards the stage. This can be solved by air stalling again but it's risky.
This technique could also be used to stop stage spikes when you fail a tech. This could save you from the bottom blastzone if you spam side B and then
quickly spam up B. But when you're trying to tech a spike, a failed tech is like the Spanish Inquisition. Nobody expects the Inquisition.
Edit: Seriously thought this technique was popular and widely known. Surprised @

and @
Player-1
didn't know about it, thought I learned it from Zee (Maybe it was either Ranai or Zinoto, idk). Oh well, The more you know, hopefully this becomes a key part of pro villager gameplay. (Still going through your videos @
zeezee
because, call me crazy, but I learned this from someone; I'm sure I didn't subconsciously come up with this.
