axiiiiiiiii
(AKA Axi, AyeItsAxi, dotaxone)
I also have several side projects online, including twelvefortynine, SuperAwesomeBertram126, Tekashi 6ix7even, braindump10, and bassgirlz, a side-project with my girlfriend.
There are probably more side projects out there, but I struggle to remember them all.
1249, or twelvefortynine, comes from the position of the letters a, x, and i in the alphabet. 1 for A, 24 for X, and 9 for I. That is why axiiiiiiii has 9 i’s.
