Stay pressed is a dismissive comeback meaning "keep being upset, I don't care." Black American AAVE roots. Same as the entry earlier; appearing again. Not concerning, just slightly rude banter. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.
