Speaking in a slow monotone, especially on a highbrow or difficult to understand topic, in a mind-numbingly boring manner; akin to a lullaby droning puts listeners into a deep slumber in places where sleeping is inappropriate.

The act of being either drunk or high and just sitting around doing nothing. This is not something to be proud of, you aren't socializing with girls or doing anything progressive. You are killing your buzz and no one likes a drone.
Steven last night was straight droning, he was drunk out of his mind just chilling on the couch.
