Nicki Minaj's Thirst-Quenching Tweet

Okay, look, you big dummy. The joke here is that Nicki Minaj made an extremely ridiculous and vulgar boast about herself. The cat's face is supposed to be the reaction of anyone reading that tweet, because it's so shocking and over the top. It's a classic example of a reaction meme, where you show what people think about something crazy. Get it? Good.
