This word has two vibes. First, the literal one: "Ang **matunog** na sampal na narinig ng buong barangay." (A resonant slap heard by the whole village). Second, the chismis/career version: when a name is "ringing bells." "Uy, **matunog** ang pangalan niya para sa promotion." It means someone is famous, influential, or the talk of the town.
