Also, very much looks like a rain leak. That line in the middle is where the rafter is so that spot didn’t get water damaged. Though you’d think it would just soak underneath it. I suppose it could be leaking just above it and splashing both ways. The brown coloring is what happens when rain water drips through shingles and insulation.
I am trying to figure out if you are casting that dick photo on the ceiling, or if the dick on the ceiling is casting a shadow that looks amazingly like you.
Either way, penis ensues.
Looks like about $100 in repair bills to me. Add a zero or two if the roof is leaking, not just the sink in the bathroom above.
(Yes, it looks like a penis, but I think what you’re seeing as “balls”, I’m seeing as the glans - that is, it looks like the wall has an erection that pointing into the room.)
