Something people say when they actually infact never let you know.

Whether its an event, something for sale, or any overall expectation. “I will let you know.” Its almost like a curse, its a clear “No”, with a skin of false hope.
James: “I will let you know when its available, Mark.”

*10 years later*

Mark: “What ever happened to it, James?”

James: “Bro, I told you I will let you know. Be patient.”

Get the I will let you know mug.
One of the greatest insults of all time. Originally said by Johnathan Andrew Wicker, Junior on June, 18, 2019
Johnathan said this to Edan, "Okay, goodbye, Edan. I just wanted to let you know that I enjoyed the good times we've had. However, I truly hate you--like, I absolutely hate your fucking guts," Edan killed himself shortly after
