what the FRICK is "💜 core"

like I've seen some here and there like "mama a girl behind you" and "Ellie and Mason house" but like why? are they supposed to be memes or something more like what makes them different than a normal meme? Also what is the meaning behind the purple heart behind it like who the frick looked at that and thought"yeah let's turn that into a worldwide internet trend"also the who saying is then in lowercase and the last word is randomly uppercase like "mama a girl behind YOU💜" like vro stop screaming at me I didn't know there's a girl behind me(ー_ー;)

okie I gotta go now this thing is turning longer than a regular essay I turn in
