for no good reason

Arbitrarily, without cause

For no good reason describes an action taken without adequate justification or logical explanation.

The phrase often expresses frustration or bewilderment at seemingly arbitrary behavior: He just started yelling at me for no good reason.

It can also downplay one's own motives: For no good reason, I decided to rearrange the furniture at midnight.
