Yes, beat me to it.
I would also suggest some kind of common warning if riding with friends. Maybe something along the line of: "Rockets away, on your left!"
The worst thing is when you are in a paceline and you have to wait -- snot dangling -- until you take your turn at the front and can drop to the back and launch offending rockets.
