Slickdickery 

Deceitful and underhanded behavior that often involves extra-marital relationships, trickedy and cheating

John, an obviously unhappily married man, was engaged in blatant slickdickery when he slipped the young woman at the bar his hotel key and a note asking her to meet him later. He later compounded his bad acts by slapping some trickedy on the situation when he called his wife and told her he would be late due to an unexpected, yet imaginary meeting.
