IS there a name to this trick?

It starts out like split the atom. split bottom mount, finger under the yoyo, then instead of feeding one string into the yoyo, you thread both. Then you pull, and it loops you finger twice, and ends just as a sleeper.
I dunno if i explained that well, but if you need a video to know for sure, i can upload one.

Sounds like some sort of ripcord variation.

Its essentially just split the atom with one extra wrap.

i would agree with samad and Dyonch but i have no clue what you’re talking about could post a vid?
