Smack you in the smonking

This is what this rather cute helpful and nice son of mine has taken to saying.

Now I'm not certain where the smonking is or how he's gone smack me or anyone else in it but if anyone else has experienced smacking in the smonking before. Let me know as between him and the other one screaming all day. I'm going to go explode.

Role on Monday when I can get some rest at work.
