The expression "drop a dime" originated during the era of payphones in the United States. In the past, to make a call using a payphone, people had to insert a dime, which was a 10 - cent coin. As payphones became widespread, inserting a dime into a payphone became synonymous with making a phone call. Over time, the phrase evolved from its literal meaning of making a phone call to a more figurative one, indicating reporting or informing someone, often in a way that suggests giving information about something, sometimes in a context of snitching.
