This entry can loosely be described as videogame folklore. The interviewer (D) and the informant, C, were playing a game called Super Smash Bros for the Wii, a widely popular fighting game with well documented analysis for every character, stage, and since two players tend to face each other from a list of characters, every potential matchup as well. There are many unwritten rules that players follow to observe proper “etiquette” when playing the game. The game is played with 4 lives “stocks” and set to an 8-minute timer. The first to force their opponent to lose their stocks is declared winner. It is proper tournament etiquette to fistbump before games start.
This interaction occurred after both players had chosen their characters for the next game. The process of “striking stages” happens in order to preferentially pick stages for the next game to happen on.
D: let’s strike stages. I’ll go first, strike Dreamland
C: strike FD
D: strike PS2
C: Alright, so Yoshi’s
*both fistbump*
The interviewer notes the gesture of fistbumping as an unsaid mutual agreement that both players can proceed to the next match. There are no explicit rules stating players must fistbump to play the game, of course, but even in friendly play this simple gesture indicates you have a working level of respect for your opponent. It conveys a “no hard feelings” attitude that works for both parties, winner or loser.
