Frequently
mentioned in classic S/M porn, this is a light, braided latigo single
tail with a silky attachment suitable for actually hitting
people.
A skilled thrower can get an audible low-toned
“pop” out of it, but it is not much of a noisemaker. It can make
a soft, brushing contact, propel a palpable puff of air or make
full contact with less skin damage than small, thin fiber "cracking"
or “cutting” poppers.
