bone in 

A bone in occurs during intercourse between a male and a female, when the female has exercised her vaginal muscles to the extent that she is able to force her labia through the base of the male's crotch, absorbing a large portion of his pelvic region.

It can also occur during sex between two males, where the receiving male has exercised his anus enough to perform the act.

Scholars are still unsure whether this came before or after the bone out.

I love my girlfriend, but I'm afraid she may want to bone in.

If you're on the road to prison, it may be valuable for your well-being to master the technique of boning in.

bone in ham

very similar to the pressed ham which is mooning a person through a window where you press your bare ass against the window with one twist. The bone in ham can only be performed by a male. He tucks his entire junk, frank and beans, between his cheeks right before pressing the ham.

We were on vacation in OBX and my boy was just about to get laid when I gave him and his girl to be a nice bone in ham. Bon apetit!
