It means, Adore Delano and Rosé, I'm sorry my dears but you are up for elimination.
It´s time for you to lip-sync... for your lives! Good luck, and don't fuck it up.
The lip-sync song is...Conqueror by Estelle
I´ve made my decision
Adore Delano- EliotWhi (Shantay you stay)
Rosé- CoolblueP123 (Sashay away)
