What does TMI mean in texting? “Spare me the details”

TMI means “too much information”. A long report won't earn it, but one line about a roommate's habits easily will. It's not about length. So what is it about?

TMI stands for “too much information”, roughly “spare me the details”: a reaction to unnecessary personal details about health, arguments or someone's habits. It's not about length: one sentence can be TMI. You can say it about yourself, too: Sorry, TMI. It's informal; in work messages, people don't reply like this.
