The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Drugged Lipstick is a similar idea, but I don't see a Sister Trope for tongue studs linked to that page... wait a minute... (idea)
I checked Poison Ring. Its description says "While rings are the most commonly used poison holder, any item of personal adornment can go here." I think I found it!
If not for this anchor I'd be dancing between the stars. At least I can try to write better vampire stories than Twilight.
Hidden Weapons (it's hidden inside the mouth, basically)
Poison Ring and Unusual Weapon Mounting fits too
We can never truly eradicate the coronavirus, but we can suppress its threat like influenza
I think Poison Ring is the best fit, thanks!
Will go ahead and nth listing it under Unusual Weapon Mounting as well, because that's a novel one.
No Time Like The Past, an Orion pirate has a miniature hypospray with a toxin concealed in what appears to be a ruby tongue stud, which she uses to kill a Red Shirt. What would that fall under? Unusual Weapon Mounting? A bizarre and deadly variation of Sleight of Tongue? They're in a brawl when she uses it, but it seems likely it was intended for. . . shall we say, gentler circumstances.
