Unfortunate names

Every time I drive to and fro KL - Tg. Malim it always cracks me up whenever I pass by Batang Berjuntai and Batang Kali. I know it's juvenile to be snickering at these unfortunately named places but I just can't help myself. I've always wondered who named these places, and why? I'm well aware that meanings and connotations of words evolve over time but I'm sure there was a perfectly good reason why these places were named as such. When I was in the boarding school there was a kid who came from Batang Berjuntai and we used to make fun of him all the time. Poor guy! I heard a few years back there had been an attempt to change the name Batang Berjuntai to something more prosaic but I don't what know happen to that name-changing campaign. All the road signs still say Batang Berjuntai. Hypothetically, if I'm from either of these two places would I be embarrassed to tell people where my hometown is? Hell no! I'd announce it loudly and proudly that it is from these places where I get my overflowing masculinity and unbounded virility because this is THE reason why they got their names in the first place! In terms of the cool factor I take Batang Berjuntai over Kuala Lumpur any time.
