A Wolbes
Blow, but the opposite. You take a hit, hold the smoke like it's your last breath, and then you swallow it. Later, you burp and all the smoke comes out like you just cursed the air.
I took a hit, held it in for 2 minutes, and then burped. My roommate thought I had a lung infection.
My friend swallowed his smoke and burped in my face during a Zoom call. It was legendary.
I took a hit and then burped at my dog. He ran out of the room.
