The "4B movement" is a South Korean feminist initiative advocating against traditional gender norms and societal pressures on women. "4B" stands for rejecting biyeonhons (marriage), bihaengsangs (childbirth), biryeon (relationships with men), and bisexuality as a forced societal norm. It emerged as a response to patriarchal expectations and gender inequality, empowering women to reclaim autonomy and challenge societal conventions.

“Hard-launching" refers to the intentional showcasing of one's amorous partner in public, either in person or on social media, without hiding any details about said partner. It is considered by many to be the first sign of commitment in a new relationship.
