Participating in something.
Cultural Background
Using 'messissä' is a way to signal that you are 'cool' and 'relaxed'. It breaks the stereotype of the stiff, silent Finn. The phrase is a point of pride for Helsinki natives, as it originates from the city's unique historical slang. In modern tech companies like Supercell or Wolt, 'messissä' is common even between bosses and employees. The phrase is a living artifact of the deep linguistic ties between Finland and Sweden.
The 'Oon' Shortcut
