I well recall back in the days Street Fighter 2 ruled the world, before we had magazines and whatnot to tell us what the moves were called. So me and my fellow arcade rats had our own names- Guile's "flash" or "Sommersault" kick, we called a "Rainbow kick". Chun Li's Spinning Bird Kick was the "helicopter kick", and her heel stomp was the "pogostick".
The most interesting one, though is Ryu's Shoryuken-uppercut move. I remember EGM beating us over the head, that it's called "Sheng Long". And that was the answer to the great mystery, when Ryu says "You must defeat Sheng Long to stand a chance." that meant that the Shoryuken move was invincible. (On it's way up) So, it made sense to me. But I haven't seen "Sheng Long" applied to that move since EGM used it! It's always "Dragon Punch". Now, I haven't kept up with Street Fighter since the CPS1 days, I don't know if Capcom's officially said Sheng Long is something else or not.
Anyway, those names stuck. To this day, I call them "rainbow kick", "helicopter kick", "flaming torpedo" (vs "Psycho crusher") and "Sheng Long".
What about you?
