On a very long, hot busride/carride with very few rest stops, how your butt gets really sweaty. Also happens on a piano bench.

Due to lack of aeration between two butt cheeks, sweat accumulates in the crevice and may cause squeaking noises while walking. May also manifest as a stain in gluteal region while wearing biking shorts.
Midwife wonders for a moment, unsure whether the woman in labor has broken her water or has a bad case of butt sweat.
