User blog comment:NoooooYWouldUDoThis/Dipper's real name!/@comment-27877549-20160324122007

Here's what we know so far:


 * it's embarrasing enough to prefer "Dipper"


 * it has an unknown similarity to "Mabel"

"Abel" might work. Or, even more embarassing, it's a girl's name that starts with M, like Mabel: Monica, Meredith, heck, for all we know, they could be Mabel and Mabel!
