Nicki Minaj Sparks #Bigfoot Trend About Megan Thee Stallion, Trade Disses

Nicki Minaj and Megan Thee Stallion are at each other's throats right now after trading shots on respective diss tracks -- but Nicki's going low ... swiping at MTS' extremities.

It all started on Friday, when Megan made good on her promise to continue to fire back at her critics from the Tory Lanez trial ... and released a new track titled "Hiss" that picked up where the last one, "Cobra," left off. While going off on haters, she also shaded NM.

Meg starts the song clawing into her ex-boyfriend Pardison Fontaine further (“He can't move on, can't let it go/He hooked, nose full of that Tina Snow) ... and fans think she went on to throw jabs below the belt at Nicki Minaj and her husband Kenneth Petty!!!

As we’ve reported, KP is a registered sex offender and Meg let her snake bite sink deep … rapping, "These h**s don't be mad at Megan, these hoes mad at Megan's Law/I don't really know what the problem is, but I guarantee y'all don't want me to start/Bitch, you a p***y!!!"

Megan’s Law is not only a cool name flip, it’s the name of the federal law that makes it mandatory that registered sex offenders have their info made public … venomous lyrics indeed. There's another line in there that mentions R. Kelly, and some believe this too might be some sort of reference to Nicki -- although the connection isn't entirely clear.

Anyway, Nicki immediately went into attack mode after the song dropped, liking several anti-Megan tweets, including many that made fun of the size of her feet.

She also previewed a new track of her own -- which is currently unnamed -- that she recorded almost immediately after hearing Meg's new track ... and some of the lyrics are absolutely scathing.

One line in particular caught people's attention -- Nicki raps, "Bad bitch she like 6 foot, I call her bigfoot // the bitch fell off, I said get up on your good foot." Nicki has also been liking a ton of memes/pics that depict Megan's feet (which Nicki seems to think are quite large).

The bigger shot here, though, is the fact that Nicki is referencing Meg being shot by Tory Lanez -- something her fan base loved to hear, but which some have said goes too far.

Anyway, in the wake of all this ... #Bigfoot soon became a trending topic on X, and Nicki hissed back further at Megan on IG … clowning her flow to make the H-Town hottie sound like some sort of UGK wannabe. Like we said, their back-and-forth has been brutal.

Megan dropped an IG Story laughing at the drama she caused online but Nicki claimed to have the last laugh seeing her name trend online.
