Dis-member Edit Meaning

1.

After having sex missionary style, ask your girlfriend to turn over so that you can begin doggy style. While she's turning over, secretly replace your piece with a dildo of the same size and stature (make sure she can't tell the difference.) Once you start doing it with the dildo, after a while, fall off the bed leaving the dildo inside of her making her think that your junk fell off.

"I was hittin' my girl from behind when I decided to pull a dis-member on her... She almost had a heart attack when she thought my shit fell off."
