I have found a way that works most of the time... Normally you can locate the person who is standbying by their red connection bar. Have your whole team wait for him to hit sbye, and as soon as he does (before you go to blue screen) your whole team sends him a friend request and it lags him out.
This also works real good during btb, cause you know you always have someone lagging out. If he is in the red and has an x on his name, everyone send him a friend request with a nice long voice message attached.
I found this out the hard way. One night while being standbyed, i sent the guys a friend request to play a custom (redemption on my ground). Of course he standbyed, but when he did all of my team members got a friend request from his team members lagging them out.
If the process doesn't work you can always cancel the friend request and repeat. Remember their connection has to be almost gone for this to work.
