A person you know that only pukes in the toilet while no one is watching at a party most likely due to the extremely fast consumption of alcohol, either by means of shotgunning or bonging. Usually, a closet puker will deny that it ever happened.
Did you guys see Jayson puke last night?

No.

Oh yeah i forgot he is a closet puker. He pukes when no one is looking.
