I personally believe that I've been in a short-lived "wet bulb" situation twice in my life. In both cases, in the Amazon, pretty much at the equator, at some of the hottest days of the year. 40-45C, humidity near a 100. A cold shower does nothing, it actually makes it worse as it activates your body to warm up. Stripping naked does nothing. Sweat just streams down the entire body as if a tap is open. It's near impossible to keep up with drinking water. It was short-lived as the weather was extremely variable, but the feeling of being completely unable to cool down despite throwing everything and the kitchen sink at it, is memorable.
