When engaged in the coital act, the man spreads maple syrup all over his partner but leaves her back covered, then rolls her into missionary position. After finishing, the woman should be stuck to the bed (and more importantly, horrified and flailing while trying to escape). Thus, a Canadian Trap Door.
"Joey took Anne down to the Comfort Inn and gave her the ol' Canadian Trap Door. Luckily Canada has free health care because they needed to operate immediately."

When, whilst having sexual intercourse with a women or performing the act of cunnilingus, one manually inserts one or multiple fingers into the anus, some going so far as to probe deep within the rectum, to engage in “anal play” in hopes of discovering whether the female currently being explored would be interested in later engaging in anal intercourse.
