Salty Neck

When one has a neck with a member of the of the opposite sex and happens to have bit of a twist... To begin, the female of the two sexes first has a romantic experience using her lips on another male private region, and she begins to suck passionately until he "Blows his load" as one would say. After this experience for the lady, she then moves onto a different male, with the intention of passing the previous victims fluid into the other males mouth (while he is unaware of the previous events that have occurred.) Hence the term "Salty Neck"

When your hand is sweaty and you proceed to slap someone on the throat .
