Pontacing 

During the early hours of the morning, having sex with someone because you are sexually frustrated.

Pronounced pon-tack-ing

Oscar and Becky sneak off early one morning into another room in the house. Jens and Jones are in the room they left.
Jones: Where have they gone?
Jens: I think they have gone pontacing!!
