"Aggressively don't care" is essentially when you flip your shit at people for talking about something because your sick of hearing about it. For me an example of this is when my friends are constantly going on about going clubbing and on about the 5th or 6th "I don't care" I end up saying something along the lines of "HOLY FUCKING SHIT, SHUT THE FUCK UP ABOUT IT ALREADY. I'VE ALREADY STATED I DON'T GIVE A FLYING FUCK ABOUT IT MULTIPLE TIMES NOW SO SHUT YOUR FUCKING HOLE ABOUT IT BEFORE I SHUT IT FOR YOU". Another example for me would be about fan fictions. I mean really, i do not care about fan fictions even less about fan fiction crossovers and tend to get irritated by people like a friend of mine who like to go on and on about fan fictions and what not.madwarper said:"Aggressively"... "Don't care"... Does not compute.
If I didn't care about something, I certainly wouldn't be aggressive about my indifference. I'd be more, you know, indifferent.
