Looks like people tend to throw the word "Simps" around too loosely (which is just a shorter term to a simpleton). Here's a real example of that shit means:
A simp is someone who donates $8000 to some random popular streamer chick dancing, who's also in a relationship mind you, whom you will likely also never meet in real life. That's a simp.
A man visiting his wife at a hospital for COVID19 is not a Simp.
