Shampoo that while it sound like it would be pleasant when you read the label in a store, really sucks big walrus cock when you take it home and use it; forcing you to dump it in the toliet or down the lavatory drain and purchase a new bottle of some other variety.

Not to be confused with shampiss, shampee, shampiddle, or shampotty.
{Mike, at store}: Hey Chris, didn't you just buy a big-ass bottle of shampoo a day or so ago?

{Chris, at same store}: Yeah Mike, but it was shampoopoo! It was Suave Lotus Pedals but it really smelled like shit so I got rid of it!
