How do you define gay, with Mario?
Gay as in never taking unnecessary risks, never approaching unless it's safe, never try to bite into baits, camping with shield and good spacing. Gay in the competitive sense is playing as conservatively as possible. And I fully condone that playstyle for Mario, given that he's fundamentally a
very defensive character in the sense that his best strategy is spacing and reacting to approaches. Unfortunately this happens to make the Mario ditto VERY frustrating.
Mike pretty much outgayed me last time I met him. He just chose to play with extremely low risk, and in the 2nd and 3rd matches of my set, only moved after he considered the situation safe, like if he knew I was going to shield, or after I made an unnecessary approach.
Anyhow instead of Up-B oos, I highly suggest learning to use U-air out of shield. It's Mario's most practical out of shield option besides B-air imo. 98% of all N-airs out of shield should be replaced with a U-air as far as I'm concerned. Yes it requires you to be technical, but as a bonus, it also makes you angle shield upwards which is great when you realize one of Mario's weaknesses is small shield size.
