Tic-tac-toe, put the circle in the square, now X is up
After the “O” is used in tic-tac-toe, the other player uses “X”. Basically, it is now XV’s turn.
The next X will also be the fifth X in the picture. XV — X 5.
Side note, circle, square and X are all Playstation buttons, but more likely alludes to the Xbox symbol (which has an X in a circle) and he loves games.
Possibly a bigger reference to his past and possibly one of his best earlier mixtapes, where he expressed most of his nerdy attributes, Planet Squaria: The Square in the Circle. Which capitalizes on taking everything nerdy (square) and making it cool (circle). He’s been doing that for years.
