shampoo ambush 

Known in scientific terms as 'Shampupicus Abushulance". It is when a shower cap is pulled over an unsuspecting victim, who is then squirted with shampoo, and then scrubbed verociously with toilet bowl scrubs. This is known to happen to people who refuse to shower.

"Did you see that Seth kid today? His hair was like a mirror!"
"Yeah, we should totally shampoo ambush him..."
