Half + Seven

basically the idea that an age gap is fine, as long as the younger is half the olders age plus seven years.

"Dang doesn't she look a little young for Jim?"
"Well, ya know what they say, Half + Seven."

Half moon swoop

A sex position in which the female, or bottom, is in a back bend position, while the man, or top, is on arial silks with and erect penis. He then swoops back and forth as he inserts his dick in the vagina or anus til climax.

The half moon swoop should never be attempted!
