Chain Pain

"You know what the chain of command is? It's the chain I go get and beat you with 'til ya understand who's in ruttin' command here!"

- Jayne, Firefly

Related to Whip It Good and Epic Flail, sometimes the chain link is all you need, without the weight at the end. In less realistic works, skilled users can make Instant Knots with it.

A Badass Biker will often do this in a rumble. Also very common in 80s movies with street gangs and among fictional Japanese delinquents. See also Fighting With Chucks, Variable Length Chain and Chained By Fashion. Sub Trope of Improvised Weapon.
