The “Cool S” is a graffiti sign in popular culture that is typically doodled on children’s notebooks or graffitied on walls. The exact origin of the “Cool S” is unknown, but it may have originated from geometry textbooks and has appeared around the early 1970s[page needed] as a part of graffiti culture. Contrary to popular belief, the symbol has no ties to either the U.S. clothing brand Stüssy or to the character Superman, though Stüssy did conduct an interview in 2010 with Jon Naar, a pioneer graffiti photographer with many works including this S, dating back to the 1970s.

The “Cool S” consists of 14 line segments, forming a stylized, pointed S-shape. It has also been compared to the infinity symbol. The “tails” (pointy ends) of the S appear to link underneath so that it loops around on itself in the same way as the infinity symbol does. The “Cool S” has no reflection symmetry, but has 2-fold rotational symmetry. As illustrated, a common way to draw the shape begins with two sets of three parallel, vertical lines, one above the other.
