Whoa that rig looks a little small for that banger lol, don't put too big of dab in there or it might fall over. lol jk. That gives me an idea to have tiny rigs paired with massive thick bangers. Anyway, I dunno why they're called that, I'd like to know too. I wondered why the titanium ones were called nails. I first heard the term banger to refer to quartz, but also the word bucket. Bucket makes sense obviously, but not sure about banger.
