What do people do in the first 1:40 seconds?

It irks me when my team just hides under turret during this time. Are they afk because they believe this time isn't important? No it can't be, they are spamming laugh. What ends up happening is that we get invaded because they were just jacking off instead of providing vision in our jungle/river. What makes it even worse is that botlane, that same botlane which was under turret, blames our jungle for dying to the invade, when it was their fault in the first place for not preventing it. I can't do much, I'm at topside, and can only watch helplessly.
