Not going to lie, something I feel guilty for having done once or twice before, always 'against' a very insistent and ego driven skatepark kid (in my defense, they really had to be the caricature), was give them a simple stare at the beginning of the game and just announce 'I'm going to give you all of SKATE in a row and yet never pop my tail', then proceed to do just that because I have a gazillion of pseudo-tricks where you don't pop. Otherwise I'm the boring dude who goes through all the 180's, then pop shoves, then kickflips. I'll also adjust to the other skater's repertoire like it's a rehearsal and I'm not trying to fuck it up. Just if they give up on etiquette first and start doing weird shit I'll give them some of mine.
