You may have heard kids and teens screaming “six-seven” or seen the trend on TikTok. It’s one of the hardest slang terms to define on this list, which is likely why it’s the most-searched word. Six-seven has many meanings that can vary depending on the context. Some say that six-seven is similar to the phrase so-so, as it’s sometimes paired with the hand gesture of both palms facing upward while both hands alternatively move up and down. Six-seven could also be a reference to NBA player LaMelo Ball’s height. It’s possible that others could be hinting at the lyrics of rapper Skrilla’s song “Doot Doot.”

Some people believe that six-seven is so overused that it has lost all meaning and is now just a funny meme. Mr_lindsay on YouTube does a great job of explaining the phrase in the video below. 

On the serious side of the list is the word bop. It might sound innocent enough, but it’s often used as an insult to people (usually women) who are viewed as promiscuous. The word is also typically used in cyberbullying and is considered offensive. People usually credit the song “Lala Bop” by rapper Almighty Rexxo, which features explicit sexual language, for the word’s origin. As part of a 2023 trend, some social media users would tag others with the song and the phrase lala bop, implying that the target was overly sexual or presented themselves in an immodest way.
