I can't even

Used on blogging sites, mostly Tumblr, is an expression that denotes so many emotional responses that the user can’t even comprehend what has been said or seen.

The complete, sudden onset of the cessation of brain activity, brought under the presence of acute stress, which fully affects the person only a short time after it strikes them. Said person, under the duress of the symptoms, demonstrate their affliction by alerting to others that they can't even, in reference to their inability to deal with the symptoms, or their inability to perform simple actions which have been made impossible by their afflictions.

When you literally can't even! When your emotions are so fucked up that you just can't even.

This phrase came from social media like Instagram, usually when a post is funny or strange. Now it has evolved into another "typical white girl word" like "starbucks" or "chipotle" .

Can't begin to understand, tolerate or believe. Incredulous

I can't even is used by the whitest if white girls. The phrase basically means something the girl can't process due to her lack of knowledge of the world outside of Instagram. Usually followed by the response "Then don't!"

When a certain someone gets so excited or upset about something, they resort to talking like a white chick in a Starbucks line.
