An originally Slovenian food that looks like a fried filet of fish and is usually served with tartar sauce and a lemon, like fish would be. However, when you take the first bite you realize the terrible truth: it's cheese. Fried cheese.
"So how was dinner last night with Lori and her parents?"
"Not so good, playa. They pulled the old cheesefish switcheroo on me."
"Oh shit man! You fell for that one again? That's rough!"
