(Can be in D1 or D2)
Mine just happened yesterday while patrolling the Moon.
I killed a Nightmare Ogre point-blank with a grenade launcher (blowing myself up in the process) and he dropped an exotic.
It was Monte Carlo. I almost died of laughter.
So I guess if you want an exotic, just perform a ritual sacrifice.

First exotic (I think,i know it was my first RNG exotic) after a crucible match. I was 5th on the leaderboard, it was Suros back in D1 before TDB. It became my staple gun, I had 5 of them by the time TTK came out 4 of which were random drops.
