Take a Chachi 

A dump. A turd. A log. A crap. A steaming pile of shit. Completely useless and fetid human waste.

Hey man. I just ate 13 tacos. I gotta take a Chachi!

Hot Chachi 

A reverse of the ever popular Shocker where you put 2 fingers in the ass and one finger in the pussy. (2 in the stink and one in the pink)

This chick said she was freaky and likes the shocker so I pulled a Hot Chachi on her.

Fuck You, Chachi 

A dismissive exclamation used to get rid of someone.
This is a masculine version of "Bye, Felicia" based on Scott Baio's political rants, referencing his role on Happy Days.

THEM: "This place sucks. You guys are so boring. "
YOU: "Fuck You, Chachi" (Said with a dismissive wave)

chach/chachi 

A guy into the following: his fraternity, spring break, Dave Matthews, sports bars, chain restaurants, Abercrombie and Fitch, thinly-veiled misogyny. From the character "Chachi" of "Happy Days" and "Joanie Loves Chachi" fame. Oddly, Chachi himself did not fit the above criteria; yet, he embodied the essence of trying way too hard and having no fucking clue.

At my cousin's bachelorette party, we ended up at Senor Frog's - full of chaches. I had to bail.

Hot Chachi 

N. A method of getting drunk where the alcohol is delivered directly to the blood stream by means of rectal absorption. The preferred method requires insertion of an airline shooter in the anus and standing on ones head. Named after Chachi from the TV show, a good boy that never drank.

James hated the taste of alcohol but he liked getting drunk so he started his evenings with a Hot Chachi or two.
