What is draws the short straw.?

"Drawing the short straw" is a common idiom that means to be chosen or designated for an undesirable or difficult task or situation. The origin of the phrase comes from the practice of drawing straws to determine who would perform a task or be designated for an unwanted responsibility. The shortest straw would mean that person was chosen for the task. The phrase is often used in situations where no one wants to be chosen for something, and the unlucky person who ends up drawing the short straw is generally considered to be the least fortunate or unlucky among the group.
