👉 "Upseize" is a slang term in South Africa used to describe someone who has overestimated their abilities or accomplishments. It's often used as an informal way of saying "upsize," which is the process of getting bigger, larger, or expanding beyond one's current size and capabilities. For example, if someone says they've "upseized" their job offer, it means they have gotten a bigger offer than what they were offered initially.
