the.com/rolling hitch

means A knot used to tie a rope to a pole, rail, or another rope so that it holds firm under lengthwise pull but can still be slid along by hand when slack.

from Rooted in the practical vocabulary of sailors and riggers, who needed a hitch that could grip a spar or a taut line without jamming — 'rolling' points to the knot's job of resisting a pull along the object it's tied to while still letting the rope be rolled or adjusted by hand. It belongs to the same family as the clove hitch, just evolved with an extra wrap for bite, and its exact first use is undocumented, as is common for working knots passed hand to hand long before anyone wrote them down.
