Every normal man must be tempted at times to spit on his hands, hoist the black flag, and begin to slit throats. - H.L MenckenWhat does it mean to hoist the black flag?
To hoist a black flag means to wage war; because, to hoist a white flag means to accept truce. The black flag is a reference to the flag generally used by the pirates-a black flag with a skull and two bones crossed below it. The meaning of the entire quote is that every time, truce isnt the most acceptable option. Sometimes you have to stop thinking about agreements and start fighting againt the enemy.
Become a pirate A flag denotes your allegiance.... to which nation or ruler or company.... the black flag means we have none... we are privateers.
