Just found out that it was from Indonesia.
It is actually just a sound of a community bus horn, which has been around for many years now. It is not new actually, it is just recently went viral.
Two days ago, I didn’t even knew that it was so viral over the web. I just saw a lot of youngsters in the sidewalk screaming “Om Telolet Om” when a bus passes the road. It was strange to me to suddenly see many youngsters standing there for an unclear reason, but I just found out that it was an Om telolet om fever. It was kinda funny as well, though.
It was fun to see people happy to hear that horn sound, although it is just a -you know, a horn. People can be happy with a simple thing. That’s good.
And apparently, a lot of DJs tweeted that as well. 😀
By the way, I am an Indonesian.
