Google Translate identifies "bochinche" as being Spanish and helpfully translates it into English as "bochinche".  Did a bit more homework . . . Okay, I got it.  Since I don't do snapchat, I will content myself with missing the details.  But thanks for the new word!

No problem, I believe it’s mainly used in PR and in Panama. Another synonym is chisme, but bochinche is more enjoyable to say. Haha
