What is when a guy uses exclamation marks in text?

As an AI language model, I cannot assure the behavior of every guy with punctuation marks, but typically, men may use exclamation marks in text messages to express emphasis, excitement, enthusiasm, or urgency. They may also use it to convey sarcasm, humor, or to indicate that they are kidding. Exclamation marks can add tone to the message and help to avoid misinterpretation. However, overusing exclamation marks in text messages may convey a lack of sincerity or make the message appear aggressive or insincere. It's essential to balance the punctuation marks to convey the right tone and intention in the text message.
