Definition
To prepare or keep something on hand against unexpected needs.
How it's used
Originally referring to the practice of keeping a guard dog or a small amount of cash at home for sudden emergencies, this phrase now almost exclusively relates to stocking up on household essentials like medicine, non-perishable food, or basic tools. It carries a sense of prudence and foresight, suggesting that one is preparing for a rainy day rather than just hoarding items. You will frequently hear it used to justify why someone has bought more than they currently need.

Common mistake
Do not confuse this with literally watching a door or guarding an entrance. While the literal meaning of the characters suggests guarding a gate, the idiomatic usage is strictly about preparation for future contingencies.
