Simply put, it's a fetish that you recently found and haven't accepted in your sexuality. Yet.
You: man the other day I was looking for things that tickle my fancy and I stumbled upon some lolicon...
Friend: and what happened?
You: before I knew, I was rock-hard. I feel so fucked up
Friend: as long as you don't molest real-life kids, I don't see the problem
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
