“Sharktooth” (verb) -- adults intentionally creating a positive experience or memory for young children.

Origin: While hunting together for shark teeth at the beach, parents would covertly drop one or more pre-purchased shark teeth in a child’s path, thus ensuring that the child experiences the joy of a successful hunt within their limited attention span. When searching for seashells, it may also be called “shell-shilling.”

Alternatively, as ammunition for ungrateful adults to declare to their well-intentioned parents that their entire childhood was a lie.
“I didn’t really catch that fish in preschool? You put it on my hook when I wasn’t looking? You sharktoothed me!”

Sharktoothing is when a woman is in the middle of a blowjob and bites down on a man's erect penis.
Doctor: So tell me, what caused your penis to bleed?

Patient: Well, I told my wife that we should try sharktoothing.

Linda: Hey, Bob, you want me to shark tooth you?

Bob: Are you fucking insane?
