this expression can be used when you are in a situation where you know nothing is alright but the situation isn't so serious that you can use the expression which would not only ease the tension but also make the surrounding audience laugh. is also very commonly used in the form "ist chillllllllll' to accentuate the "ill" at the end of chill
" dude i can't find my lunch card.
Ist chillllllllllll. "

" i just got mugged but ist chill "

(girl slips and falls on we side walk)
