Translation please
Betting the Under is a reference to the Over:Under bet that is available for most sporting events. In this context it implies that something bad is about to happen to the OP or the thread.
As an aside my frieds & I also set an over:under whenever somebody gets married. Mean? maybe. Funny? Oh Yea, especially when the marrige is an obvious mistake.
We had one where the over:under was before the reception started.
