It's not a Poi - It's not a Meteor... it's something in-between. I did a search and might guess that somebody has already touched the topic, but I'm not sure.
The origin of this might (most likely) come from Kung-Fu, where a person is handling a long rope with a dart at the end.
This, as visualisationNow, IF we replace the rope with a chain and the dart with a monkey fist... whadda we get?
A "Single Meteor"... IMO perfect, if the last bit of the chain is a fire rope (whereas manipulation get extremely complex then)...
