Oh, pretty simple.

“Both women are personifications given form of incredibly popular games, the left, blonde one representing “Fall Guys”, a piece of media that involves content and stunts similar to the show “Wipeout”. The one on the right represents “Among Us”, which is incredibly similar to the card game “Mafia”, with some non-noteworthy additions. The “Fall Guys” woman is presenting a stress relieving toy which functions similarly to bubble wrap but is reusable, commonly known as a Pop-It (written here as “Pop It”), with an attitude of pretending not to care, despite actually caring. This is a common character trait throughout media, with the first example popping into my head being the “Tsundere”, a trope in Romance Japanese Animation. The woman representing “Among Us” is incredibly overjoyed to recieve this, and responds with much affection, to the shock of the “Fall Guys” woman. The “Fall Guys” woman reacts by attempting to keep up the uncaring attitude, in which the “Among Us” woman sees through the false attitude and responds to the friendly insult by effectively calling her a spoil-sport. The specific term used, “sussy baka” has a decent history behind it, but to summarize, it came from the general negative connotation of Western fans of Japanese Animation using Japanese words in regular life, specifically “baka” being idiot, and “sussy” is a shortened version of Suspicious, a term now commonly associated with Among Us, due to its breakout popularity.”
