Also known as: 怒りマーク, 青筋, 💢, 愤怒符号
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.
