This is actually from my code, and this is the function in question being called, and yes, I'm bisexual. I never was into drag, but I respect that community.
Ahh my bad I got whooshed. I don't get the music, but I'm on mobile Firefox with ublock origin so maybe that's why. I do get the rainbows and ponies, though. Its beautiful.
Looks like it to me. Probably something that takes an object (element, component depending on library, etc) and starts the “drag and drop” process so the object “moves” with the mouse.
