rofl! Oh dear Deo, yes, I've had some nasty encounters with BO in my life. Kinda goes along with excessive partying for days in the middle of fucking nowhere without sanitation.
Worst composition I ever had to suffer through:
1 car, a hot summer day, a 6 hrs drive + 4 people returning from a 3-day-trip without showers or even a catlick, but instead free access to meals with excessive garlic and meat, gallons of hard liquor, smoke both from cigarettes and fire, and only one set of clothes. The worst of all: one of the girls in that car was seriously menstruating. Of course, in the beginning, there wasn't any problem because I had been on the same trip, but after I had used a lake we had come across to get at least semi-clean and NONE OF THOSE FUCKERS HAD THE FUCKING DECENCY TO JOIN ME, it became... intense.
At one point, I was ready to just get out and hitch-hike my way back home. Of course, as I said, I was still only semi-clean, so my chances to be welcome in any normal, civilized environment were zero.
I, personally, remember this roadtrip as a first taste of hell.
