To not realize something that's so obvious, that it's as obvious as an actual dot on the end of one's nose. When something is so super-obvious, but someone is totally unaware of it, it's a total dot-nose situation.
Dude, you've got wet shit all over your shoes, do you have any idea how dot-nose you're being!?
Quit moaning dude, no need to get all dot-nose.
