While playing Super Smash Bros. Brawl with people online I've encountered what I've dubbed YES moments, after Dane Cook's line in his Struck by a Vehicle routine. The bold and underline are important. They happen when I see a setup and just know what the other person is going to do a couple seconds in advance, letting me counter and pull off a big smash.
The best examples are with meteor smashes, used to spike people into the pit while they're trying to jump back to the platform after I've hit them off. Sometimes I'll see the angle of their trajectory as they fly off and will immediately be able to predict where they'll be as they recover. This is important because most meteor smashes have a delay on their activation and/or they only last a short time, so you have to be very precise in both positioning and timing to hit with them. So, when I send someone flying, I'll get that YES feeling, jump out to intercept, and pull off a perfect meteor smash to KO them.
It's hard to describe the sense of satisfaction I get when I pull off one of these moments but it's totally awesome.
I also have an amusing little SSBB-related story that happened a couple days ago: I was lying in bed, waiting to fall asleep, and was imagining various scenarios of playing Samus vs Wolf and ways to get back onto the platform against his edge guarding. (Yes, I think about these things even while not playing.) One of them ended with me landing right on Wolf's up-smash and being sent flying into the air (note to self: don't jump directly off the edge over Wolf). And then my left index finger reflexively curled, in the same motion as if I were pressing the L button to do an air dodge and slow my flight through the air. It made me pause as I realized what had just happened and then I laughed at how ingrained Smash Bros. is in my brain.
