O-crunches

Somewhat inadvertent "crunches," or quick contractions of the abdomen, that some women perform during orgasm; especially during multiple orgasms.

Alternatively known to as "O-sit-ups."

"Oh! Oh! Oh! Oh! Oh! Oh! Oh!" Tami cried during her "workout." She was too lazy to get up, put on spandex, lie on the floor, and do actual crunches, and preferred instead to stay in bed while Josh gave her o-crunches.

O Party

An O Party is a group of people who have had sex with really large objects until they have stretched the anus/twat into a huge O shape. They then gather around in a circle, still exposing their stretched holes, around a group of men. The men then ejaculate into each stretched hole. Other things may be used to pour into stretched holes, like syrup or oil.

It caught me by suprise that the party I attended to last week was actually an O party!
