Moving the ball from one side of the pitch to the other, trying to work an opening: If you can't get in down the left then keep the ball, pass sideways <God No!> or even backwards <explodes in purple-faced rage> and try to work it in down the right side.
I Googled it for a better explanation and (my cookies presumably) got this
http://www.betterfootballcoaching.c...ss-the-ball-to-team-mates-to-keep-possession# as the top suggestion, it includes the following, which I think is spot on:
Younger players tend to want to attack the opponent's goal at every opportunity. This enthusiasm is a good quality in young players but it can often affect the team's rhythm because each player that receives the ball wants to immediately dribble or run forward in search of a goal.
To combat this, you should teach your players [and some of the fans

]
to remain patient in possession and wait for the correct space and time to attack. Young players often try to force their way through pressure rather than turning away and quickly passing back to a team mate in space.
By passing the ball from side to side, your team will keep its opponent on the run. This will eventually tire them or create attacking opportunities.
I've not even looked at the drill, so I can't comment on that, but that's a very good description of possession-based football.
The actual definition he uses of
recycling possession is lower down the page, but I think amounts to what I said at the start.
FWIW I don't see this as the right way to play football - for me there isn't one. And to some extent it's a fashion inspired by recent Barcelona teams, which like any system has its shortcomings - but whatever it is, it's not negative.
