Jeans that can be put on/taken off very quick and easily.
My girlfriend wasn't wearing her sex jeans so she had to take a moment to pull of her tight skinny jeans. The moment was completely ruined.

Sex which occurs in a large crowd or public place, the participants try to keep it discreet by only unzipping their jeans to do the deed.
Lucas: I was at the club last night and witnessed so much jean sex, it was unreal !

Shannon: Yeah, same ! The lack of nakedness really threw me off..
