The effect when you drink alcohol the day after getting extremely drunk and it only takes you a quarter of the amount of alcohol to get you equally as drunk as the night before.
The shampoo effect really got Brittney tonight, she only had one shot and now she is peeing in the refrigerator!!

Calm down, It's probably just shampoo.

They were just shitting us.

Get the mud shampoomug. "Yeah, then I gave her a load of English Shampoo... Told her to make sure and lather it up real nice."

Get the English Shampoomug. 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."

Get the Shampoo Effectmug. 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.

Get the Dry Shampoomug. 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."
