Don’t Give A Shit 

It means that you are not interested in or worried about something or someone; that you place no value on something, an event or a person; that you do not care and are uninterested. It means that you place less value on it than you do on a turd, says it all really.

“Malcolm had a hissy fit when he found out he wasn’t invited to your birthday bash.”
“I don’t give a shit.”

Don't Give a Fuck Mode 

Don't Give A Fuck Mode (DGAF) is a temporary (or permanent for some people) period of time when a person chooses to "not give a fuck" and do whatever he/she pleases without worrying about the consequences.
