Spandex slut usually refers to someone who enjoys wearing and fetishizing spandex fabric and incorporating it into their kink or sexual expression. They may be especially drawn to tight-fitting garments such as leggings, bodysuits, singlets, sportswear, or full-body suits. The term is usually self-applied and emphasizes enthusiasm for the material rather than a particular dominant or submissive role.
Spandex is a stretchy woven/knit fabric containing elastane that delivers a specific texture, shine, compression, smell, and wearing experience.
In this usage, slut isn't considered an insult, but is a reclaimed term used to describe someone who is especially enthusiastic or devoted to a particular kink.
