ATF

As pertaining to Dr. Sheldon Cooper's (primary character of The Big Bang Theory) tendency to think of himself as the comic book hero, The flash. This acronym is quite understandably extended out to be "As The Flash"
Meaning both that you are pretending to be and are considered to be The Flash.
