"lol dipshits." - Satyr
And now they all think they're named "dipshit"
Fun thing to do in a crowded place is yell "Hey, dipshit!" and then laugh at everyone who turned to look.
"Heh, is your name 'dipshit?'"
Now, this Satyr, he asked if he could have your name and you replied by stating your name? Or did you say "yes" and then state your name? I see. I think you have a strong case that the Satyr stole your name. I'd be happy to represent you pro bono, do we have a deal?
Hmmm. Satyr thanks them? That implies a debt is owed.
Well if you wanted them you shouldn't have given them away!
Demand for them has just skyrocketed, you all saw it!
If they don't remember their own names when they get them back you could randomize which name goes to who.
Similar happened to me my first dnd run :^(
Honestly, the least bad thing that could have happened.
Yeah they should be grateful he didn't ask for their classes
May i have a hand?
Friends, Romans, countrymen, lend me your ears!

I do this to my storyteller when I play my Sidereal Exalt, abuse of Name-Pilfering Practice is probably my hallmark.
I haven't played exalted in forever. Never got a chance to play a Sidereal, but the fey folk were like that too.
How does it play?
It's very much like in OP, except I can just pickpocket a target's name when they aren't looking.
Like a lot of Sidereal charms, it's deceptively useful but dependent on setting up a situation to make it good. I use it to either fuck with someone powerful (a CEO whose name can no longer be used by anyone is paralyzed) or to learn the name of someone I just met so I can convince them that we've met before to improve their initial reaction to me.
In one instance a villain summoned the Wyld Hunt and just as they appeared I swiped her name and proceeded to command the hunter because they were summoned by [villain's name] and that was my name (now, anyway). Storyteller ruled it worked because it was a fey creature.
Fey was probably delighted inside to see that trick. Very good trick! Now a reason to come back to get their name from you and stay in the story!
I, of course, sent the Hunt after one of my enemies. I'm not going to waste the opportunity to play "let's you and him fight".
~~My catspaws~~ The rest of the circle are sometimes frustrated with my antics, but I'm too useful for them to ditch.
You're supposed to leave your name at home when goong to the Feywild
A dude with a permanent erection stole my name?
Do they all wake up in Sigil?
