What Does It Mean To Stock On Someone?
To “stock on” someone is not a grammatically correct phrase or idiom in English. It is possible that the intended meaning was “to keep stock of someone,” meaning to monitor or keep track of someone’s actions or whereabouts, but this would not be a common or natural phrase. It is also possible that it is a misunderstanding or misspelling of “stalk,” which would mean to follow or observe someone closely and persistently, often with the intent to harm or harass them.
