Your biggest DIY spill, that is. I don't mean dumping over your bottle of Boba's Bounty while refilling your carto. Not even your biggest one, but your most discouraging one. Did you back your car into the 50-gallon drum of 100% nic in your garage and have to bulldoze your house? (mods: completely joking....) Did you knock over the gallon jug of VG onto the new carpet? Did you finally come close to your all-day vape, and the cat knocked over your last .08 ml of The Magic Flavor? I don't have a big one yet; I have been paranoically careful, but accidents happen.
