look up any word, like pussy:
 
1.
An adjective describing someone who, it is plain to see, can't see. Sometimes hard to distinguish between this, and a moron

Note: Sometimes confused with blindingly obvious
*Thud*

Foolish Guy: "Hey, why does that guy keep walking into walls?"

Cool, wise guy: "Well he's obviously blind... Well, that or he's just a moron"
