protruding surprise
1. Something that is protruding and surprizing at the same time. Often the protrusion is the cause of the surprise. 2. When a woman conceals a strap-on/dildo and you are fucking or about to fuck, when suddenly she unleases her toy on your anus. 3. When you wake someone up by sticking something in their ass.
#1: "My ass still hurts after my girlfriend decided to give me a protruding surprise..." #2: "Wow! What a protruding surprise!"
