There is a common definition of “dance etiquette” in English, or rather it was accepted:
“I. A common usage is to give a partner a “striptease” before you go to dance, usually by doing a round or back bend, or a back flip, or doing something like that. This is done either to let someone know they are going to dance or as a greeting of sorts.” (Emmanuel A. Beres, A Handbook to Dance Etiquette, 2nd ed., 2008; reprinted by A.P.C. Press, 2001.) A lot of dancers may feel intimidated or uncomfortable in accepting their partner’s “striptease” on a dance floor, and not necessarily because you are giving them some kind of physical affection or greeting, you are just being honest. Some may feel pressured or confused about the dance floor because of this practice. In addition, other dances may demand a dance show; therefore, even if you are “just a few steps ahead of your partner” you should still give them some kind of greeting or attention because you are trying to work out what the choreography of the dance is.
When should one do a dance “striptease”? The first thing to remember is that your purpose in sharing your body with your partner should not be to put your partner at ease by showing off your most intimate parts (i.e., when you do a back flip, or do a belly flop, or the backside of a belly flop). All of these are common dances that are designed to elicit arousal and are also generally viewed as a sexual and sexualized dance (such as the backside of a belly float).

“A dance where sexual innuendoes are more commonly seen than in other dances, where the dancing is based on the act of dance itself, where the dance is not intended to be enjoyable to dancers and more focused on the dance, and where the dancers may be inexperienced in expressing their sexual desires, such as the female ballroom-dancer, the female samba dancer, the dance instructor or the dancer’s partner or the choreographer of this dance.” (Emmanuel A. Beres, A Handbook to Dance Etiquette, 2nd ed.; reprinted by A.P.C. Press, 2001.)
So, for example, with a backflip, why would you be “stripteasing”? You’d put your partner at ease by showing off your upper body before dancing the dance,
