A term for a poorly written sex scene, most commonly in fanfiction or sometimes original
Internet works, describing sex scenes that are badly done, unrealistic, and
pathetic. This can be because the characters are out of character, or if it is full of errors or generally badly written. The term was coined on fanfiction.net combining 'sex scene' and 'sucks'. It is usually used by people supporting better writing and good
grammar.
Person One:
Wow, that was horribly clichéd and unrealistic sex!
Person
Two: Yeah, what a sux scene.
