Closet Drinker 

A person who pretends to hide his/her drinking problem, yet everyone knows what a drunk mess they are.

Brandi likes to take shots alone in her room, then come out and stumble around the apartment. She's such a closet drinker!

Drinkers Closet

The name given to a bed when you’re drunk and do your best to get stripped beneath the sheets.
Often results in a major struggle and waking up half naked with pants round your ankles and your shirt half pulled over your head.

Ken- Man I was so smashed last night, I tried to get undressed in my drinkers closet but I lost the battle and fell asleep half way through.
