“Kepo” is an Indonesian slang, which comes from Hokkien language (usually used by some communities in Medan, Palembang, and Pekanbaru) and then become a loanwords in Singlish (Singaporean-English). “Kaypoh” which means really curious defines a condition when a person wants to know about everything.
Yet “Kepo” is an abbreviation stands for “Knowing Every Particular Object“, defines the same like what “Kaypoh” means.
In English “Kepo” has a similar meaning to “nosey” (also nosy). “Nosey” means too interested in things that do not concern you, especially in other people’s affair.
• She’s such a nosey person!
• Keep your nose out of my business, you nosey Parker!
A: You know what, Rere is having an affair!
B: Really? That man must be crazy!
C: (out of nowhere) What you guys are talking about?
A & B: You’re so Kepo!
