Wattf(Wattf) is the combination between wat and wtf(What the Fuck). It is generally used in a similar manner as wtf, but it emphasizes on a reaction based of confusion, not anger as wtf is sometimes used to express. Some have tried to shorten wattf although it's short enough anyway and some ideas include: watf and attf.
Wattf are you doing with that squirrel?
