It's similar to a kerb stomp.

You put someone's face against a kerb like if he was kissing it and then you hit him in the back of the head. Bloody and potentially lethal.
In the book the City and the City by C. Miéville :

" A young man called Avid Avid left bleeding from the head after taking a kerb-kiss from a racist..."

A scene at the beginning of American History X where Edward Norton totally gives a kerb kiss to a guy.( He kills him and then goes to jail)
