1.
Someone who really tries to accomplishes something, but is just confused. They almost reach their goal but in reality they just end up fucking it up. Its a nice way of saying, "fuck up".

The origin came from some guy who really fucked up at something and they always wore blue shoes.
Congrats this year's blue shoe award goes to you! You almost had it but you fucked up!
