When you are having sexual intercourse while wearing a condom, and the condom breaks, leaving the remains pushed to the base of the shaft.
Last night me and my girl were having sex, afterwards I found out I was turtle necking. I hope she isn’t pregnant.

The act of pushing a circumcised glans into the shaft of the penis, as if to turn it inside out. Then wrapping the scrotum over said inverted penis, and holding this formation until stuck. The penis will slowly reverse to normal in a turtle-neck-like-fashion.
