Fat Man
Second atomic weapon
Fat Man was the codename for the atomic bomb dropped on Nagasaki, Japan, on August 9, 1945—three days after Little Boy struck Hiroshima.
The name referenced the bomb's round shape.
Together these weapons ended World War II and introduced nuclear warfare to human history.
Lowercase, a fat man is simply an overweight male.
