Gilbert Arenas is living up to his "No Chill Gil" Instagram handle yet again and this time it's at Juvenile's expense.

The retired former NBA All-Star took to his IG today and reacted to a headline about the rapper being arrested recently over a $150,000 child support debt by rewriting the lyrics to his classic record, "Ha."

"You gotta go too court (HA), you got served with a subpoena for child support (HA)," Arenas wrote as his IG caption, which is accompanied by a photo of Juvenile's mugshot. "That was they nerve (HA), you ain't even get a chance to say a word (HA)....I know you just ain't gonna let THE COURTS come and punk (HA) stunt and front ya (HA) str8 up run you (HA)."

Good grief.

In closing, Arenas even rewrote the opening line from Juve's hit "Back That Azz Up" by saying, "Child support taking over FROM the 99 into the 2000's."

Bruh! Gilbert Arenas is a damn fool! 

We're absolutely convinced that there isn't anything off limits to No Chill Gil because the former baller seems to have nothing but time for the 'Gram.
