look up any word, like pussy:
To ejaculate on the lower part of the back after performing doggy style, mop up the junk using a super absorbent yellow towel. Hold the towel in your fist then donkey-punch the submissive and yell out ShamWOW!!
I had the best shamWOW finish last night, and no mess afterwards!

Dude, I gave my girl a nasty facial last night, but don't worry, I "Sham Wowed" her 'til she was squeaky clean.

When a guy you thought was hot does something so unsexy that your vagina dries up in an instant.

The male equivalent of anti-viagra
Yeah, girlfriend...Rick and I were really getting it on and I was ready, and then he pulled out his tiny pencil dick and it totally shamwowed me....

1)That towel-absorbee you see every now and then on t.v. advertised by Vince Offer, a guy with a huge eyeball.

2)You use it dab up spills, then ring it dry, like magic.

3)The absorbee I put in front of my tub so I can jump out and roll myself dry, like magic

4)The last towel you'll ever buy, until it begins to stink

"It's a towel, it's a wipe, it's a mat, it's, it's...A ShamWow!"

"Now look into my eyeball and tell me you don't want one!"
