IOGTLTT is an acronym for "It's Only Going To Lead To Tears". Used when someone says they are going to do anything from the mundane to the amazing, and another person uses the acronym or full phrase to reveal how they think the persons idea will turn out.
As used in person or on a forum:
"I wanna throw a Ford 460 in my Honda Civic!"

"Dude, it's only going to lead to tears."

Obviously the acronym "IOGTLTT" would only be used on a forum or in an e-mail.
