I'm not a writer, but I used to compete in college level latin and ballroom dancing. At the competitions I went to, there often were "fun dances", which are competitions with interesting restrictions like "back-to-back tango" or "straight-legged samba". The most common was "same-sex rumba".

Fun dances are judged by how much fun the dancers look like they're having and/or how amusing their dancing is. So for same-sex rumba, lots of people used exaggerated sexy styling, because it's fun to mess around with and it gets lots of crowd approval.

So it would be totally plausible for a ballroom comp to have a same-sex (dance of your choice) competition. And for Malik and Altair to try to dance as sexily as possible, regardless of what their relationship normally is, in order to win the competition.

As a side note, in normal competition there's restrictions on what moves are allowed. For example, "syllabus" competitions only allow moves in the syllabus for that level, and lifts aren't allowed at any level (even "open" levels, i.e. non-syllabus). For fun dances, though, pretty much anything goes, and those who could do flashy moves like lifts often did. So anyone who wants to write a scenario like this could include whatever move they want without worrying if it's allowed in normal competitions.
