D&D 5E. Me: Gnome Wizard. Early in the campaign, we're in a dungeon facing off against some nasty dudes. DM mentions metal codpieces on their loincloths. I ask if that is technically part of their armor. DM says yes.

I have Shocking Grasp in my prepared spells. Mwahahaha. The rules say, "You have advantage on the attack roll if the target is wearing armor made of metal. On a hit, the target takes 1d8 lightning damage, and it can't take reactions until the start of its next turn."

I shock his balls clean off and he dies.

The rest of the campaign, @generikat's husband T. playing the Basic Bitch Human Fighter keeps asking if I wanna grab the junk of almost every foe we meet. F*cker.
