A laid-back conference call, so called because you spend most of it chilling.
Optimally the majority of the teleconference goes by with the phone muted, listening on speakerphone or headset while you lean back and sip whiskey.
"Yo dog, what's the pin for today's conference chill?"
"I didn't have anything going on Thursday afternoon, so I dialed into the conference chill and leaned back for a bit"
Like a conference call, but chill.
Yo, you gonna hop in on this conference chill?
