"Dat Boi", a colloquial pronunciation of "that boy," is a phrase associated with various images featuring a 3D character model of a green frog on a unicycle, which are typically accompanied by the captions "here comes dat boi!" and "o sh*t waddup!"
In July 2014, FunnyJunk user tehbestever posted a photoshopped image identifying a young boy named "Dat Boi" as the "most wanted criminal arrested" as "dat boi". In June 2015, Tumblr user phalania submitted a post with the message "here come dat boi!!", followed by a picture of the video game character Pac-Man with the caption "o sh*t waddup!".Although the original post was removed, reblogs managed to accumulate over 75,800 notes in the next year. On April 3rd, 2016, the Facebook page Fresh Memes About the Mojave Desert and Other Delectable Cuisines posted an image of a green frog riding a unicycle with the caption "here come dat boi!!!!!! / o sh*t waddup!". The frog graphic originates from the Animation Factory Essential Collection 3.
