Megan Thee Stallion doing her signature ad-lib
In addition to "hot girl" and "hot girl summer", Megan Thee Stallion is known for her signature ad-lib which involves sticking her tongue out, creating a "creaky", audible "agh" or "blah" sound. (WOW BIG WHOP!)
In August 2019, Twitter created an official emoji for this tongue symbol which could be spawned directly after the hashtag "#megantheestallion".
This symbol also inspired the cover art of her EP Suga which was revealed in March 2020.Megan originated the viral catchphrase "hot girl summer" on social media.
It is a derivative of another of her most-known catchphrases, "hot girl", also derived from "real hot girl shit". She first used the phrase in a tweet on April 14, 2018.
It later appeared on the Fever album cover, which read, "She's thee HOT GIRL and she's bringing THEE HEAT."
She defined the term as "women and men being unapologetically them, just having a good-ass time, hyping up their friends, doing you."
Megan Thee Stallion officially trademarked the term "hot girl summer" in September 2019 after applying for it in July of that year.
A song of the same name was released on August 9, 2019.
