Your mumther is a kind, motherly person you met on the internet. They love all of their children and hope everyone gets along. Chatting with her can quickly turn into an exchange of heart emojis and other shows of affection that can brighten your day.
"Hey, that chatroom chick is always looking out for me. She's totally my mumther."
