Adult Fanfiction (like "lemons") but of an extremely explicit nature. Lemonade being a fanfic with Lemons being the sex scenes in it, Hard Lemonade is used to describe the fanfics of an extremely explicit nature, usually written in gratuitous detail, leaving nothing to the imagination.
"I've read some good Harry Potter lemons before, but this latest update was nothing but hard lemonade! I had to take a shower after it!"
