What is Dat Boi? Dat Boi is an internet meme that became insanely popular at the beginning of this year. This meme originated off a Facebook page with the caption "Here comes Dat Boi" "Oh s*** Waddup!". Dat Boi is a green frog on a red unicycle. He originates from the AP Physics 1 Essentials on page 179. The frog has become fairly popular, but is now on the decline. The meme is easy to input into any format, because you can insert it where anyone one says "Who is that?". Although the meme is funny, there is some interesting physics regarding the frog.
