A short-hand way to write "what the fuck", a cross between "wtf" and "what the fuck". Bears slightly more emphasis than "wtf", while still being quick to type, and technically does not constitute swearing.

A Starbucks hidden menu item including a grande nitro cold brew with two added shots of espresso.
A 16 oz grande nitro cold brew contains 280 mg of caffeine, a shot of espresso contains 75 mg of caffeine.
Accounting for the 2 oz of lost cold brew, a WTFU contains a whopping 395 mg of caffeine!
I pulled an all nighter and I need to stay awake for my exam, I better go to Starbucks and get a WTFU.
