shit in my face 

To be mistreated outrageously badly by someone. To disregard or defy someone.

Despite all the things I did for him, he just shit in my face.

shit on my face 

To shit on one's face is to "mess", or kid with one's self. Similar to "Nah, I'm just shitting you".

Person a)"Dude, your Mum just died..."

Person b)"...Omg..."

Person a)"LOL! Nah I'm just shitting on your face!"

"<suprising comment>"

"Dude, dont shit on my face, are you serious?"
