Poll: what’s the hole you cover with your thumb on a glass pipe called

Where are you from, when did you start smoking, and what do you call it?

Edit: so the original thread was debating if is a generational or regional thing so that’s the kind of trends I’m looking at...

So far I’ve heard the following locations:

- Carb: NY, NC, FL, TX, CA, WI, CO

- Choke: BC, ???

- Shotgun: ???

Seems random so far, but majority of people call it carb
