When you or a (usually applied to outfits) object or etcetera is simply not giving slaying or giving you life. Mostly said like, "It's not giving what it's supposed to give." The other way is it's giving. Meaning it's giving you life or slayin'.
Person A: "Girlll, that outfit is simply not giving."
Not giving a shit has to do with the level of care given. Not to be confused with "not giving a fuck" see that definition. Not giving a shit means that you literally don't care enough to take action.
For example, Dillon may not want to go to work today. If he doesn't give a fuck, he will still go, but be filled with apathy. If he doesn't give a shit, then he won't bother showing up.
not giving a fuck is not a matter of how MUCH effort is put into something, but rather how much one CARES about whatever amount of effort they happen to have put into something.
For example:
man 1 can work hard all his life and make millions and literally be not giving a fuck about what has happened in his life
AND
man 2 can be homeless and mope and be sad about his position in life, therefore he fails in not giving a fuck and in this senario he is the "loser"
As opposed to the common misconception that man 2 gives less of a fuck because he hasn't worked a day in his life.
A sentence commonly used to express a feeling of utter and total disinterest in a subject, person, action or remark.
This phrase presents itself in real life most often under criticism...
