Anything which can happen between a couple. There is no set definition as to what it may be, but it can be said that it issomething that someone who is not part of the couple would not want to be around when it is occurring.
Casually used to define a piece of bread, preferably before toasting and the paler the colour, the better the hanky panky spanky janky tastes.

"WOW! That hanky panky spanky janky tasted impeccable! For extra flavour, i added my dead husbands pubic hairs, tasted juicy and crunchy and delightful!!!!!!!!!!!
