In forums, you can't use curse words, so some people say Gently Caress in the place of "fuck". i.e. we gently caressed all night. Therefore, a Novelty Gently Caress is a Novelty Fuck. When someone has sex with someone they normally wouldn't because that person offers something different, a novelty, such as having sex with an obese person, a paraplegic, or someone of different race (or maybe even gender).
I heard Sue and Ginger hooked up. Sue says it was a novelty gently caress, though.
