I had no idea what a Fetty Wap was 1 minute ago, and I feel slightly dumber now knowing the answer.
My first guess was that it was going to be some sort of new foreign food that I would have to seek out... nope.
i call bullshit because 1 you would have misread it as wetty fap as the rest of us did and 2 would have thought it was something related to porn.
