A butt hole that is penetrated so forcefully that it rips open the size of the Grand Canyon and starts leaking brown liquid hot magma uncontrollably. When gas is released from the ripped and butchered anus hole the wind force is similar to that of El Nino.
Molly, your ass is in the primary stage of anal fission: its gaping. I need a gas mask for your anal fission Molly, its getting stinky back here.
