Apple kissing

When two prolapsed anuses touch eachother.

Alice and I got very drunk and tried out some apple kissing last night.

Apple Kisses

When two people eat an apple (Usually a Pink Lady) and kiss afterwards.
The popularity comes from the sweetening effect the apple has on both parties lips, as well as freshening of the breath.

"Do you fancy a Pink Lady babe, ready for some Apple Kisses?"
"Oh my god we had apple kisses it was so romantic!"
"He tasted so good when we apple kissed."
