We have a place called "Moe's" that sells southwestern food (fast food, but fresh). They specialize in burritos and such. Now, I don't eat typical fast food (Wendy's, McD's, Taco Bell, etc.), but I will occassionally grab something that is "fresh" fast food (no, not Subway).
Well, I usually get the "Triple Lindy." I also get extra meat. So I get this huge burrito (the size of your head) and stuff it with extra meat (steak) and black beans along with cheese, lettuce, tomato, salsa, fresh jalapeno's, black olives, onion and gauc.
After eating one of those, I can cause death with my ass. The combo of meat and black beans with the rest of the stuff creates some of the worst gas I've ever had.
So yes, black beans can definitely spark some terrible problems! Just don't go to a club/bar afterward or around any women you hope to hook up with.
