스윽 (seueuk)

*swish* — a smooth, quiet move

What it means

A soft, sliding movement. Not a real sound — it shows something moving smoothly and quietly.

Where you'll see it in manhwa

• Someone slides a note across the table
• A character leans in close
• A hand slips into a pocket

How to say it

Romanized as seueuk. It's a motion effect (not sounds at all — these show how something moves) and its rarity is uncommon.

• 살금살금 salgeum-salgeum — *sneak sneak* / tiptoe
