Holy Christ, someone shit in the pool!
Calm down, It's probably just shampoo.
Yeah, look, it's half a snickers bar.
They were just shitting us.

Similar to how adding water to a nearly empty shampoo bottle gives you "more shampoo", giving a small amount of alcohol to someone who was very drunk the night before, returns them to a drunk state.
Bro 1: "Damn, why is Alex so drunk right now? He's only had two drinks."
Bro 2: "It's the Shampoo Effect, he was plastered last night."

Shampoo in a spray can for when your kids are driving you nuts, making a mess of your house, your husband doesn't know how to lend a hand and you have zero minutes for yourself.
I have a parent-teacher conference in and hour with no time to shower. I guess I'll just use the dry shampoo to make my hair not look like it hasn't been washed in a week.

The phenomenon of when it takes just a little bit of booze to get drunk the day after a night of many alcoholic beverages. The same way as when a bottle of shampoo is almost empty and it just takes a little bit of water to make more shampoo.
"Man im feeling drunk after these 2 beers for some reason. It must be the shampoo effect going on from all those shots I did last night."
