Pek nga

Pek nga, often written without spaces or with hyphens (e.g., Peknga or Pek-nga), is a Filipino slang term. It is derived from reversing the syllables of the Tagalog word ngapek, which itself is a colloquial term.

The general meaning of pek nga is "really?", "is that so?", "you don't say!", or a similar expression of surprise, disbelief, or mild skepticism. The intensity of the surprise or disbelief can vary depending on the context and tone of voice used.

It's considered informal speech and is commonly used among younger generations in casual conversation, particularly in online settings or texting. While generally understood, its usage in formal settings is not appropriate. The phrase often serves as a conversational filler or a reaction to something unexpected. The original word ngapek and its reversal, pek nga, are frequently employed to subtly question the veracity of a statement or to show amusement at a situation.
