When, in the summertime, instead of having a regular shower in your bathroom you jump in a chlorine-filled pool to disinfect yourself from the sweat and sunscreen that you've accumulated on your body since the last time you had a shower.
Person 1:"Yo Mon, you going upstairs to have a shower or what?"
Person 2: "Nah man, I'm gunna go have a chlorine bath. I like the way my hair curls after one anyways."
Person 1:"You smell really..clean. Did you have a chlorine bath?"
Person 2:"Yes actually I did, right in my own backyard!"
When, in your group of friends, there are two friends who believe they are closer than anybody else and will continually ignore or make fun of everybody else because they are so "close" and have SO many inside jokes to share with each other. This quality makes them act and seem like dicks. Their friends that have been isolated sometimes question whether or not these two friends are actually dating because they appear to be so "close".
Person 1:"Hey, are the Dick Twins coming over tonight?"
Person 2:"Nah man, they're fine when they're by themsevles with us, but when the both of them are together I just can't deal with them."
Person 1:"Hey-not everybody's here yet-where are the Dick Twins?"
Person 2:"I dunno, they bailed on me man-they're probably out on a date or something because you know how "close" they are."
When a person, who may or may not be a douchebag, commits several obnoxious actions that would make them seem as if they were on a douchebag rampage.
For instance, this person could all of a sudden pull out a pair of aviators, twist their cap backwards, chug a beer and attempt to crush the can on their forehead, then pump up some really loud bass beats and begin to fist pump.
Also, these people could simply be considered assholes and/or attention whores, who will go on a rampage by verbally annoying everyone around them if they are not being paid attention to, saying stupid things like "Yeah bro", "Yo, none of these broads are good enough for me", or "That's why everybody loves me man".
This makes everyone around this person want to inflict serious bodily harm to them, especially to their genitals, so that they cannot foul the earth with another little shit like themselves.
Person 1:"Oh my God, did you see that guy start fist-pumping at the bar after he chugged that beer? He almost knocked his stupid visor off his head-and how can he even see? He's wearing sunglasses indoors!"
Person 2:"Yeah I saw him..he's commiting an act of Rampant Douchebaggery right now. Just ignore him-these attention whores will calm down when they see everybody hates them."
