Nucking
Heard in Mayo
The act of kissing the head off someone.
"I caught you nucking de head offa some tome beek... Fair play feenog!" Note: Nuck literally translates as head and is used in many circumstances. For example: off their nuck (crazy), pig's nuck (ugly head), upside down nuck (bald man with a beard), crusty nuck (of new age tendencies), gugg nuck (baldy head), froshty nuck (pale face), turbo nuck (huge head), bird nuck (big nose) etc.
I observed you exchanging saliva with some rather unusual chap. Well played, old fellow!
