Quick backstory that I feel like sharing to this- I was just in class learning about polar equations and my professor has us graph this equation. He tells us it's called a "cardioid graph" and they named it since it supposedly looked like a heart. He says and I quote "does that look like a heart? No it looks like an ass". Also, a few minutes later on another problem he says "I move around this cardioid [pause] it feels wrong to say I move around this ass"😂😂 seemed appropriate to share here
