What's this?

at 2:05s…

what’s that? looks like a whip thingy to get into the split bottom mount. i’ve tried doing random whipping to get into that but i cant pull it off.

what is it?
and how do you do it? (videos would be nice)

Its not a split bottom mount, its some weird mount.

I think its a houdini whip, with your wrist instead of your finger. And from a hanging yoyo, not a trapeze.

The first step of this trick.

well it kinda looks like a sideways trapeze to me cuz he’s kinda doing bione’s from there
