Where, in the process of acquiring food (whether it be in a school lunchline or drive through) you are in the process of foreplay with another, or yourself. In more extreme cases this may extend to sex but such acts are generally discouraged in public settings, exceptions do exist though.
Not to be confused with Erotic-food acquisition.
There are two types of erotic food-acquisition:subtle and stupid.
one resulting in "That guys voice kept changing over the speakers and he was breathing hard."
The other resulting in "That guy was getting head."
