"A bondage suit, also commonly called a gimp suit, is a form-fitting garment designed to cover the body completely [...] A bondage suit is sometimes used in BDSM to objectify the wearer, or gimp, and reduce them to the status of a sexual toy, rather than a sexual partner."
From Wikipedia:
"A bondage suit, also commonly called a gimp suit, is a form-fitting garment designed to cover the body completely [...] A bondage suit is sometimes used in BDSM to objectify the wearer, or gimp, and reduce them to the status of a sexual toy, rather than a sexual partner."
Kagi still put gimp.org as a search result for "gimp suit".
But I'm very surprised I didn't know this meaning of gimp, thanks!
