Slang for a sex scene or a romance scene (more often used as slang for a sex scene than just a romance scene) in a yaoi fanfiction. Often contains several creative words for cum, penis, and buttsex. Usually very disturbing unless you're a yaoi fan. But even then it's still kind of disturbing.
"I can't believe I wrote a yaoi lemon."
"I can't believe she wrote a yaoi lemon!"
"Found any good yaoi lemons lately?"
"I quit reading that yaoi fic once it got to that huge lemon.."
