Mentalism Gimmick
The other day I saw an interview where RickyEdit was saying there's a gimmick that lets you have, for example, four names, and the first letter of each of those four names spells out a word you've chosen. I'm not sure if I explained that well, I hope so. Does anyone know what it's called?
I think you might be talking about "AKRONYM BY CONJURING LAB." Check it out and let me know:

That's exactly it, thanks a lot!
