Dhmu (don’t hit me up) is a phrase used on snapchat. It is used to say “don’t text me or dm me or contact in any way.” People put on their snapchat story “dhmu” to express they are sad, or don’t feel like talking. sometimes but not all the time, dhmu is used for attention so people ask them what’s wrong.
