To repeatedly strike a prostitute until she stops biting your tongue.

As made famous by Vince Offer aka the shamwow guy.
"Prostitute Survival 101: Do not be afraid to shamwow the prostitute if she attempts to bite your tongue"

"I was with this crazy prostitute last night who tried to bite my tongue...fortunately i was able to shamwow her and get away"

"Wow, that hooker just got shamwowed!"

When your girlfriend thinks she is being cute by biting down on one of your body parts and you shout "Sham Wow Bitch!" while punching her in the face until she lets go.
Just like what the Sham Wow guy did except it was a hooker and he got arrested.

The sound classic comic book Batman makes when he punches a prostitute in the face.
"Oh no, I believe she is beginning to use her teeth!"

**ShamWow!**

It was a close one, but Batman made it out alive.
