When someone is so heterosexual that it seems to have its own aura. You know that they’re heterosexual simply by looking at them and it is so invasive and aggressive you can’t ignore it.
e.g Frat boys, dudes who wear sports jerseys and shorts in blizzards, Kyles etc.
When someone goes out of their way to be passive about things, or to just not be involved. Often, getting involved wouldn't inconvenience them, but they just don't care about that. They want to ignore it and be on their way.
(Adjective) - A category of person or organization that goes out of their way to avoid knowing or learning about something so as to avoid responsibility or duty to act.
Usually associated with someone who exhibits either a general lack of intellectural curiosity or just plain burned out in their careers so they don't even try to improve themselves. These individuals are motivated by a strong desire to be the opposite of the "go-to-guy" so as to discourage requests for help or challenging assignments.
Boy that Wally sure is "aggressively-ignorant"- when I asked for help he claimed to never have used the copier before - and he sits right next to it!
