When one finally drops a quality hot and steamy log that hangs from ass to toilet water after extreme constipation and does not realize that it has not detached from the anal cavity, causing him/her to proceed with the wiping process, and violently "smash" through the log. It is called a "surprise" because the victim usually responds with "HOLY SHIT!" or "MY BUNG HOLE!" or "DOUBLE YOU TEE EFF!"
1. "I was walking past the bathroom while my brother was taking a shit and I heard the beginning poot but did not here the ending splash that usually follows. I realized what was happening and immediately yelled 'DICK, WAIT!....but it was too late..he had experienced his first Chinese Log Smash Surprise."
2. "After 3 weeks of being constipated I had taken my glory dump, not knowing that the magnificent log had not detached. As I went to wipe (from front to back) I had my 5th Chinese Log Smash Surprise this month!"
3. "After his Chinese Log Smash Surprise, Jim's hand never recovered..."

When you are fucking a girl doggy style right before you pull out and cum in her face, you stick your dick in her ass and then you cum inside her anal canal.

After baking a normal blumpkin pie (shitting into a pie dish whilst having your cock sucked), you let your girl tuck into it. While she's chowing down, you go to the fridge and get a coconut, then you smack the bitch so hard in the back of the head with it that her face splats into your shit and she goes unconcious.
Guy 1: Hey what'd you get up to last night?
Guy 2: My wife was tucking into some of my blumpkin pie and then I smacked the fuck out of her with a coconut. Her face hit the pie so hard shit sprayed the walls.
Guy 3: Sweet I'd love to get a Blumpkin pie with a coconut surprise .
