⚔️ Origins of the Yellow Streak Idiom

The expression has roots in early 20th-century American English, with “yellow” historically being slang for cowardly behavior. During that time, being called “yellow” or “yellow-bellied” was a sharp insult, implying that someone lacked the backbone to face adversity. The "yellow streak" extends this idea further by suggesting a consistent or intrinsic quality of cowardice, symbolized as a “streak” or line of yellow running through someone.

This linguistic evolution mirrors similar idioms in other languages that metaphorically connect colors with emotions or character traits. In English, yellow unfortunately got tied to timidity—possibly from its association with warning signs and caution tape.
