Megan Thee Stallion’s snake-driven campaign slithered away with a whimper when she met face-to-face with the real deal … a bottle of alcohol with a dead snake stuffed inside!!!

The rapper is currently turning heads during a trip out in Japan that tested her “Fear Factor” meter — this after she sampled Habushu, a traditionally super strong liquor native to Okinawa.

Apparently, it’s powered by poison … the local Habu snake is said to ferment inside the container to age as long as possible — which makes for one hell of a boozy drink.Welp, Meg dove in without hesitation and asked if the potion would send her to the morgue — but she didn’t chicken out … taking a sip of the concoction, but not really liking it much.

Meg took a little slurp of the Habushu — but this time around, she didn’t drive the boat too far … docking and anchoring her experience, saying the drink was too strong for her liking. Can’t blame her … drinking dead snake, even for a buzz, doesn’t sound pleasant at all.It’s pretty funny … Meg topped the Billboard Hot 100 a few weeks back with her single “Hiss” — which was the follow-up to another reptilian record “Cobra.” But, when it comes to the real McCoy … she isn’t into it, it seems.
