The choice of words is important here ... cause MTS' mom passed away from brain cancer back in March 2019, and Megan's talked a ton about how her mother influenced her.
Back in 2021 -- while accepting the Glamour Woman of the Year award with tears streaming down her face -- she said, "I want to thank my mom because she taught me how to be the woman that I am" ... so, this Nicki diss was meant to cut Megan deep.
As for why she said it, Nicki seemed to answer that question to some extent ... reminding Megan fans that her family's constantly a "focal point" of criticism -- and she's clearly getting sick of it.
As we reported ... this round of beef popped off when Megan seemed to reference Nicki's husband, Kenneth Petty, in her new track "Hiss" -- making a "Megan's Law" reference that many interpreted as shade toward Petty's legal trouble.
Nicki responded by putting out a rap that got "#Bigfoot" trending ... but clearly wanted to make more of a statement than that. BTW, fans are kinda split on Nickin's comment about Meg's mom -- though a lot seem to feel she went too far.
