I took the game by storm, just to X men out
Taking something ‘by storm’ is to succeed overwhelmingly, which Ab-Soul (and TDE in general) is doing in the rap game at the moment, and to X someone out is a symbolic way of killing them. In order to get to the top of the rap game, you’ve got to defeat your competitors.
This line showcases some wordplay, as Storm was a character in the Marvel comic, X-Men.
Another thing to notice is that Storm isn’t a man, that could explain why he X'ed“ the men out.
Some might also say that Ab-Soul also made it snow earlier in the verse by being the coldest rapper flowing.
