blowing an o-ring

When the lips of your anus, which form an "O", stretch to such an extent due to hours on the toilet, the "O" of your anal lips tear. Thus, you have blown your O-Ring, as well as lost your anal virginity.

"OH GOD! MY ANUS!"

"SUSTIN, ARE YOU BLOWING AN O-RING IN THERE?!?!?!"

*Blood and feces proceed to drip into toilet*
