When because of recent use, a little goes a long way. Usually referred to when re-gaining an alcohol buzz. (If you shampoo your hair and ever "repeat", you know how just a tiny bit of shampoo will cause instant lather? that's the shampoo effect)
I had so much to drink last night, all it took was one beer this morning to get me buzzed again, gotta love the shampoo effect!
The act of after having sex pulling out of your bitch and shooting a steamy load in her hair. After which rub it around in her hair with your hands then pee in her hair and have her swish it around. That my friends is the Sticky Shampooing.
carm: "hey rick. what did you last night?"
rick: "i was in my bitches room and i gave her a good sticky shampooing."
carm: "oh...kickass!"
When some lazy bastard wants to clean his shower but is only reminded of the task every time he gets in to use it so he squirts shampoo all over the floor of the shower and kicks it around until the bubblesstop and he calls it clean. His logic being: Hey it works on hair right?
Guy 1: Dude! The shower looks great! Did you finally break down and clean it?
Guy 2: Nah, I just gave it the old "shower shampoo".
