You would expect to see a lipstick kiss mark on someone's cheek or on a love letter, but someone spotted the mark somewhere that has people grossed out and questioning how it got there.
It was in a toilet.
Twitter user @ClawedHumour posted the image with the caption "Stranger Things - 2018" and now everyone is trying to figure out if someone with red lipstick on actually kissed the inside of a toilet bowl.
Others just made jokes.
No one knows the real reason the lipstick mark is there so it might be a mystery that goes unsolved forever.
