The moderators and many people in the room found the presentations funny. It wasn't until later when they tried explaining their behaviour to their mothers that they even began to understand the problems with what occurred.
Circle Shake -> Titstare -> Pre-scheduled break -> Apology
And it was clear- they reacted after they saw the reaction on Twitter. Not after they saw the presentations themselves. If you had those opinions all along how could you stand on a stage and say "up next, Titstare" without even blinking?
Apparently per their Facebook apology, Titstare entered under a different name, with the Titstare name first being seen in the slide deck.
