So my gf and I managed to snag a deal staying at a hotel and getting dinner on valentine's day, and we both got so excited when we saw the spa-bath jacuzzi in our room,
even though it was a bit small.
We DID notice the warning sign about being cautious about keeping body parts away from the intake area, but didn't think it was very important (mistake).
After it finally filled up, we turned the jets on and she hopped in, and there was barely room for two, but I tried squeezing in opposite her.
As I got comfortable, I suddenly felt something strange happen. It felt like I was in a space ship and a hole had appeared behind me, and my body just tried to plug it.
It wasn't painful, it just felt like 15 vacuum cleaners being hooked up at the bottom of my spine, and I immediately pleaded with my gf for help.
I probably could have unplugged myself, but with her help I was off the intake hole within 3 seconds, but the damage was done.
I stood up and showed her my back, and she erupted in laughter at my new tramp stamp.
She later added that a benefit of the whole ordeal is that if a man is rooting me, my speedometer tramp stamp could tell him how fast he's going.

Back got sucked into the intake and plugged it, ended with massive bruises in shape of drain.
