Ass Twiddling

When one person is not active, they are twiddling their thumbs. When someone doesn't know what they are doing their head is up their ass.

Ass Twiddling is when a team is composed of people who don't take action and seem incapable of doing it, at which point, everyone is shoving their thumbs to twiddle up another's ass.

That division is completely useless. Far too much ass twiddling going on.
