not giving a shit

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.

The kitchen staff are not giving a shit anymore so they don't do their fucking cleaning duties.

not giving a shit about the Third World 

Pretty self-explanatory card from Cards Against Humanity.

Simon: Hey, what does not giving a shit about the Third World mean?
Justin: Basically it means you don't care about the problems of people from the most poor nations, duh.

Breadhead 

Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".

A breadhead is like a crackhead, but for money instead of crack.

Stink lines

As seen in illustrations or cartoons: Wavy, vertical lines rising above a person, place or thing. Denotes a foul odor.

"You didn't put enough stink lines on your picture of the teacher."
