Plural of bleeder; people or animals that bleed, or people with bleeding disorders like hemophilia.
From bleed (Old English blēdan) + -er (agent suffix) + -s (plural). Bleeders can mean both literal bleeders and is also historical British slang for a person (as in 'poor bleeder').
The term 'bleeder' was historically used to describe hemophiliacs, and the word is tinged with tragic history—many hemophiliacs were infected with HIV through contaminated blood transfusions in the 1980s, making the term heavy with meaning.
