When the girlfriend or wife of your friend gives you a kiss hello or goodbye immediately after blowing your friend thus leaving a small amount of his spunk on you that resembles frostbite.
P - Hey J, what's that white stuff your cheek?
J - I don't know. T's wife just gave me a kiss hello.
P - I think they had just snuck off for a hummer about 5 minutes ago.
J - Ewwwwww, She gave me the Jersey Frostbite
