Many cowboys couldn't spell, leading to confusion among non-cowpokes. Among themselves, words were used in context, so it made no never mind- they understood each other. I think al this has been covered before, but Here, in their entirety are the definitions (from "Western Words," Ramon F. Adams, 1944, Univ. Oklahoma Press).

"Hooley-ann- [mis-spoke as hooligan, hoolihan, etc.- see post by Mark Ross; in common lingo the original term is becoming lost].

A roping term. This throw can be made either from the ground or on horseback. The roper carries the loop in his hand, and when the chance presents itself, he swings one quick whirl around in front of him toward the right, up over his head, and releases the loop and rope in the direction of the target. As it comes over, it is turned in a way to cause it to flatten out before it reaches the head of the animal to be roped. It lands straight down and so has a fair-sized opening.
"It is a fast loop and is strictly a head catch, being especially used to catch horses in a corral. It is thrown with a rather small loop and has the additional virtue of landing with the honda* sliding down the rope, taking up the slack as it goes." (W. M. French, "Ropes and Roping," Cattleman XXVI, no. 12, May 1940, pp. 17-30.
(*Honda- From Spanish Hondon, the hole or slip ring end of the rope used to catch the animal. Gilbert y Chavez, Ch. 9, Vaquero/Cowboy Lingo, http://www.unm.edu/~gabbriel/chap9.html. (or from the publication- see post above.)

Additional on Hooley-ann - "The rope has not been slung over the horse's head, for to sling it would cause even the steadiest old horse to become excited. Using the hooley-ann, half a dozen men can rope mounts at the same time without exciting the horses." John M. Hendrix, "Roping," Cattleman, XXII, no. 1, June 1935, pp. 17-17.

"Hoolihaning- The act of leaping forward and alighting on the horns of a steer in bulldogging in such a manner as to knock the steer down without having to resort to twisting him down with a wrestling hold. This practice is barred at practically all recognized rodeos

"Also to throw a big time in town- to paint the town red."

"Hooligan wagon- A wagon used on short drives to carry fuel and water in a country where these commodities are scarce."
