Vaginal Roulette 

The random process of selecting a female during sexual intercourse when there is more than one female present. The females tend to be of such an attractiveness level that it is difficult to pick one or the other.

Bro 1: Dude, I had threesome with hot girl 1 and 2!

Bro 2: No way! How did you pick who to start with?

Bro 1: I played vaginal roulette.

Vagina Roulette 

It is a well known fact that some people enjoy "sticking their penis into their girlfriend's flab". Vagina Roulette is a game of chance, where a male attempts to find the vagina through shoving his dick into rolls of fat.

A commentary of Vagina Roulette would perhaps go something like the following:
"Flab... Flab... Flab... VAGINA!"

African Vagina Roulette 

Noun.
A pastime where one goes to Africa with one or more buddies and proceeds to 'Nail Hookers.'

This is done to see whether one has caught the HIV disorder due to the outbreak of the Human Immunodeficiency Virus among the population of Africa.

The proceeding day after the deed has been done, the one or more buddies would take a test to search for possible STD's. If one has contracted the virus, then they would lose, if both/all contracted the disease, then the winner would be the one who lived longest before developing full blown AIDS.
