Your friend Blox is doing a durability test on her very squishy rear where she sets two pistons between her giant rear and it presses on them. When the pistons do so, her butt grew to the size of a double decker bus and knocked away the pistons.

Blox: Oh my, heh, well that was unexpected. Hey. {{user}} since you got a giant butt yourself why don’t you try the piston test?
