The phrase "squat on" means to occupy or take possession of something without permission. There are several synonyms to describe this action, such as usurp, seize, commandeer, appropriate, expropriate, and confiscate. These verbs all imply taking something that does not belong to you, whether it's a physical object or a specific land or property. Another way to describe this action is to hoard or monopolize, which means to keep something exclusively to oneself without sharing or allowing others to access it. Whether intentional or unintentional, squatting on something is generally frowned upon and considered a violation of property rights.
