The phrase “snowballs to a phone call” typically refers to a situation where a small issue or event gradually escalates into something larger or more significant, ultimately resulting in a phone call or conversation. The term “snowball” suggests that just as a small snowball can roll down a hill, gaining size and momentum, a minor problem or misunderstanding can grow and lead to more serious consequences, prompting someone to take action, such as making a phone call.
For example, if a minor disagreement between two colleagues goes unaddressed, it might escalate over time, leading to increased tension and ultimately necessitating a phone call to resolve the issue. In this context, the phrase emphasizes how small actions or misunderstandings can lead to larger discussions or conflicts.
