I think unless the terminology changed since I last paid attention to the ecig scene (which is way too often no thanks to some of my coworkers) mod is short for mechanical mod which is literally just pushing contacts on a battery together and forcing it to discharge rapidly as possible by shorting it out. What do you do if the button to engage the battery gets stuck? Do you throw it out a window and run away?
It's funny though cause I'll see them go outside to go vape ecigs, and I'll say "vaping time guys!!!!" and they'll be like "yep!" but it's funny cause they don't know I'm coming back from vaping (trees).
Hate they stole our damn verb though, for many years "vaping" meant you were doing weed.... now it probably means you need 200 watts for your nicotine juice...
Sorry guys, looks like I started rambling, I posted after my morning vape.
