nw - no worries
afk - away from keyboard
wb - wall bounce
gg - good game
heart - determination to get the ball against the odds, sometimes preventing (or causing) a goal.
blocking - moving your avatar infront of an opposition player to stop them from moving where they want, useful for creating passing lanes or shooting oppurtunites if done properly.
snipe - an accurate long range shot, usually through a very small gap... looks very nice.
cherry picking - basically goal hanging, making sure you're level or just past the last defender as an attacker so you can pick up anything that run's lose and score.
parking the bus/ bussing - putting as many players as you can infront of the goal to stop the opposition from scoring, very frustrating for attackers!
rushing - moving straight towards the player fast with the ball in an attempt to catch them off-guard.
swarming/flocking - this is when everyone on your team chases the ball all over the pitch, doesn't usually work as a good player will just pass round the swarm/flock of players.
split - this is a shot or pass that goes right through two players on the opposite side, very difficult to time but very rewarding.
