Canadian Surprise

A Canadian Surprise is when during sex with a partner, you manager to swap out the bottle of standard lubricant with a bottle of 100% pure maple syrup, and when you cum you shout "GOES DOWN SMOOTH, DONTCHA KNOW!?"

"Steve and I were going steady and having a lot of fun in bedroom until he pulled the Canadian Surprise on me. I can't date a Snow Mexican sympathizer, you know?"
