AD refers to
alcoholism and
depression. Some people have one or the other, but in more severe cases some people may have both.
In the case of such an event the proper way to refer to
the condition is AD or “the good ole AD combo”
“Bro, did you hear about what Chad did
last night?”
“No, what happened?”
“He was drunk af and got
kicked out of the bar for asking
the bouncer for cocaine. then said he was going to wrap him and his car around a tree”
“Fuck, sounds like he has a pretty bad case of the good ole AD”
