Wife, daughter, or hooker
A game that is played when a middle-aged or older man is seen with a considerably younger girl to determine the relationship between the two people. Given the age differential, it's usually plausible that his female companion could be his wife, his daughter or a prostitute.
When we were in the Orange County airport, we had to play a game of wife, daughter, or hooker after seeing a smoking hot girl in her late 20's hanging out with an older guy that appeared to have a lot of money. It was anyone's guess.
