I was just thinking about what we would do at games, and I thought I'd throw a few ideas out there: 1. Just a basic chant: A few people go: A-C! The rest: S-T-L! Then keep repeating: A-C! S-T-L! A-C! S-T-L! 2. Start with a slow clap, and get progressively faster. Once the clap starts getting faster, everybody goes "OOOOOOOOOOOO" (round O). Optional: it can be done right before something happens, like the first touch or a PK, and when the foot touches the ball or the ball reaches the goal/goalie, we end with a stomp or one loud clap. Otherwise, we can just let it trail off. 3. Dunno how family friendly we want to be, but this is more tame than stuff they have in Europe. This uses the opponent's name (or city), however it fits best, in a taunting fashion: Nick-Name...Nick-Name...YOU SUCK! This can go on for a few times, though probably good to keep the number down to a minimum to have a better effect. Of course, all in good fun.
