Everyone was firing off subs from the Rolling Loud stage.  

A$AP Rocky subbing Travis Scott. Kodak Black subbing Boosie Badazz.

“She thought that I would kiss her ass, she must ain’t took her meds," Latto rapped, and then feigned cocaine use.

That line has been long assumed as a Nicki diss.  Adding the coke sniff when Nicki is a rumored cocaine user seems to confirm it.

Latto vs. Nicki, who you got?
