look up any word, like mexican microwave:
When you sit in front of an exam and look at the worksheet and you actually understand NOTHING it's called "the WTF effect". This effect often appears to people who didn't learn enough.
Person A turns around the paper sheet. "Hey, this looks easy"
Person B: "What the Fuck?!"
Person C "Looks like he got the WTF effect"
