Outside of sports, the term "hash mark" may also refer to the symbol "#" or the act of adding a "#" before a word or phrase on social media platforms to create a clickable link or tag.

The word "hash mark" originated from two separate terms.
1. Hash: The word "hash" dates back to the 17th century and derives from the French word "hacher" meaning "to chop". In cooking, "hash" refers to a dish made by chopping up meat, potatoes, or other ingredients into small pieces. Over time, "hash" began to be used more generally to describe a mixture of chopped or mashed items.
2. Mark: The word "mark" has roots in Old English and refers to a visible indication or identifying symbol. It can also be related to marks made for measurement or notation.
When combined, the term "hash mark" refers to a symbol or mark made by crossing or slashing multiple lines with diagonal slashes, resembling the appearance of chopped or mashed items (like a hash).
