Baby voice galore: They speak in a register so high, it could shatter glass (and your eardrums).
Over-the-top cuteness: Every sentence is punctuated with enough "eeeps" and "squees" to rival a basket full of puppies.
Excessive use of "like" and "literally": Because, like, literally, everything is, like, literally, amazing.
Example: "OMG, like, I literally just clutched that round! Eeeeee! You guys are, like, literally the best! UwU"
Disclaimer: Just let women exist, okay? I know the accent is annoying, but they are not responsible for society making them feel the need to sound overly cute.
