The person in the middle position of a three person threesome. To achieve the status of Lucky Pierre they must be both penetrated by the person behind them and penetrating the person in front of them simultaneously.

It can be performed by two bisexual gentleman and a lady, it can even be performed by three ladies sharing two strap ons. The possibilities are numerous.
Anne, Bob and Christie decided to have the night of their dreams. As Bob fucked Anne, Christie pegged him with her strap on, and there was much rejoicing. Bob had finally become a Lucky Pierre and could now die a happy man.

The middle person in a three-way, often erroneously reported as an all-male threesome. The person in the middle of all the action. It can be any combination of male and female partners, though "Lucky Pierre" is the term for the man in the middle.

The middle person in an all-male three way. It is not necessarily the term for an all male threesome; it is simply "the Cat" in the middle.
After a hard day in the oil industry, the Cat often likes to relax on the golf course with his partner. However, he does not get outraged when another man asks to join his twosome, because he is used to being the Lucky Pierre.
