While a girl is giving you a blow job when you are about to cum you take her head and make it face down then you cum all over the top of her head.

The word’s origins come from sham, French, meaning false or fake - and poo, slang, referring to biological excrement more commonly referred to as “shit”. Thus, one can only assume that shampoo is “false excrement” or “fake shit.”
Examples of shampoo include: Prell, Clairol, Nioxin, Suave, etc.

Have you ever noticed, while bathing, that while it takes quite a bit of shampoo to lather your hair up the first go-round, if you try to lather it again a second time, it only take a drop?

Well, being shampooed means that you were drunk the night before and it takes you only one drink to get hammered again.
Dude, I just finished the first beer of the day, and I'm totally shampooed.

Engaging in sex while shampooing your partner then Mid-coitus, one person bites the neck of the other, locks their arms and legs down and goes into a deathroll, all while maintaining insertion. Upon completion the man finishes in the womans ear and then proceeds to mushroom slap the woman being sure to leave a print.
I heard Candi and that Tranny Lizzie shampooing last night, and I saw the print to prove it! I'm gonna have nightmares for weeks...
