In Erfworld, Dance-Fighting is a Natural Ability used in combat to add a significant bonus to a Unit or a Stack. Often, the Units dance-fighting will adopt a style of dress, but this is not necessary to receive the bonus.
Knights In Stanley's Service - The Knights in Stanley's Service, populated by elite Hobgobwins, are led by Lord Stanley The Tool himself. They adopt black leather 'armor' and warpaint, wield axes, and generally have a Heavy Metal Appearance.Erf-b1-p076
Wanda Firebaugh at the Courtyard Breach - This dance-fight was planned by 'Lord Hamster' after learning that the Royal Crown Coalition had few troops that could dance-fightErf-b1-p128), while Gobwin Knob had a Master-Class Croakamancer that could lead uncroaked in dance-fighting (as well as providing a significant Leadership bonus), despite that uncroaked normally could not dance-fight. Wanda led an army of several thousand Uncroaked in a rather thrilling defense against Ansom's attacking forces.Erf-b1-p127 Erf-b1-p129
The exact mechanics of dance-fighting have yet to be explained in the comic. Most often, Dance-fighting occurs before combat rather than during, and very frequently includes chanting or singing. The units that are to receive the dance-fight bonus usually dance in formation with one another, instead of using Real World modern free-style dances. One performer typically leads the dance, which others can use to keep in sync and rhythm (which may improve the bonus, but may not even be necessary). Once combat is engaged, the combatants cease dancing, but unengaged Units continue, suggesting that the dance needs to continue right up to the moment of combat, or that dancers can maintain the bonus on combatants.

Lord Stanley's dance-fight style is inspired by the American Rock Band, Kiss. The 'Knights In Stanley's Service' (K.I.S.S.) are based on a) the Kiss Army, Kiss's massive fan-club, and b) an accusation that the band name KISS once stood for 'Knights in Satan's Service'. Stanley wears the face-paint of Kiss band-member Paul 'The Starchild' Stanley, as their names draw an obvious parallel. Stanley also quotes two Kiss songs as rallying cries against the Transylvito forcesErf-b1-p123: "Stand up! You don't have to be afraid!" with his Knights answering "I love it... Loud!" from the 1982 I Love It Loud; and "Your lightning's all I need" from the 1977 Shock Me. The quotations seem directed to the Arkenhammer itself, referring to its powers of thunder, lightning, and electric guitar.
