Procrastination is the avoidance of doing a task that needs to be accomplished by a certain deadline. It could be further stated as a habitual or intentional delay of starting or finishing a task despite knowing it might have negative consequences.
A procrastinator also mean a person who delays or puts things off — like work, chores, or other actions — that should be done in a timely manner. A procrastinator is likely to leave all the Christmas shopping until December 24th. Procrastinator comes from the Latin verb procrastinare, which means deferred until tomorrow.
