"Is there some jojo siwa dababy beef i don't know about?" asked another.
Shared a third: "Just when you thought life couldn't get any weirder, Dababy disses Jojo Siwa."
As head-scratching as the lyric may be, some fans tried their hands at guessing why the rapper would drop such a line seemingly out of left field about an entertainer more than 10 years his junior.
"I feel like he just said Jojo siwa since it rhymed," one person mused on YouTube.
Added another: "He wasn't throwing shade at Jojo ... it clearly shows that he was using her last name as in 'see why' instead of 'Siwa.'"
Some felt DaBaby used the teen star's name to start a controversy. "The Jojo line did exactly what DaBaby & other people involved in his camp wanted it to do," wrote one person. "Stir up controversy & generate views." Another on Twitter agreed, commenting on DaBaby's post, "He threw in that jojo line because he knew it would get people talking. Smart business moves only."
If the intention of the line was indeed to get the rapper and his freestyle some notice, it worked. DaBaby became a trending topic on Twitter and Google over the weekend.
Regardless of his reasoning for mentioning Siwa in his freestyle, not all of his followers are impressed by it.
"Other rappers beefing with shooters and killers while DaBaby beefing with Jojo Siwa," wrote one person on YouTube.
"That jojo siwa line was foul as hell," opined another.
Billboard has reached out to DaBaby and Siwa for comment.

Update: DaBaby took to social media to explain the JoJo Siwa lyric on Sunday night (Feb. 21). "my 3 year old princess is your number 1 fan. I bought her every product you have out. She think she you," DaBaby tweeted to Siwa. "Don’t let em trick you into thinking id ever have a problem with you. My word play just went over their heads." See his full reaction here.
