Anger Vein Wiki | Danbooru

A symbol used to represent anger or annoyance. It consists of three or four curved lines in a cross shape, representing a bulging vein or artery, like so: 💢.

It usually appears on or floating near the forehead or fist; however, it can also appear on other body parts, or even as a spoken anger vein in dialogue.

For more realistic veins, consider veiny face.
