Normally used in situations when she shows up at your front door, unannounced, bug eyed, with a strong resemblance to Linda Blair from the Exorcist!
You- Open door
Girlfriend- "WHERE THE F*UCK IS MY CHI? It's been almost 24 hours since you borrowed i!! Give it to me NOWWWWWwwwwwwwwwwwww.......
You- "Gurl, I got your back, its right there in my bathroom hooka.. plug it up and get them nappy ass curls scrate so that head of yours can spin a tad bit faster, Damn CHI-lax!!!"
2) The much cooler way to say "take a chill pill." Similar to "calm down." Used when someone is freaking out for no good reason and causing others to feel stressed or when someone is acting like a dumbass.
"Chilax, it's not like I wasn't going to pay you back."
"You're going to need to chilax on the drinking."
Also can be used in forms such as Chilaxin(2), or Chilaxed(3).
(2)Last night Johny and I, we was straight chilaxin, we didnt do a thing.
(3)Last week while I was on vacation a just chilaxed at the house.
