Watered Down 

Something that is similar to something else, but with less features. Altered so as to be weaker in force, content, or value.

The term “Watered Down” comes from when drinks are diluted with water to be made weaker. But can be applied to other things.

Arizona is like a watered down version of Australia.

Trumped-up trickle-down

A variation of a golden shower, this lewd sex act involves paying underage prostitutes to urinate on an object which represents your enemy or rival.

Bobby also seems to want Vanessa, so I grabbed his letter jacket while he was distracted to give it the ol' Trumped-up trickle-down. Can I borrow a tarp?
