Definition

An unexpected detour or task that wasn't part of your original plan, borrowed from video game terminology. Going to the store for milk and coming home with a plant, three candles, and a new hobby? That's a side quest. Life is just main quests you ignore for side quests.

Example Usage

"I went to Target for toothpaste and came out with a rug, a blender, and an existential crisis. The side quest consumed me."
