Surprise Chef 

When a girl sneaks up behind you, reaches around and starts giving you a wristy!

The definition comes from the Aussie TV show - The Surprise Chef - hosted by Aristof (A wrist off)

I was drying myself off after a shower and Karen came up from behind and gave me a 'surprise chef'!!

chef's surprise 

When you open up a girl's pussy real wide, and, disgusted by what you see, throw up in it.

If you're squeamish whenever you see private parts (you big pussy...) then the chef's surprise is the move for you.
