spitting salt 

Yelling at someone. Often used when someone is salty about something and is in an argument to take care of it.

If more intense, screaming, see "Vommiting Salt"

"As soon as i found out what he said i started spitting salt."

Sitting on Salt 

Giving a great deal of thought to something, whether it be something quite insignificant, or a life-altering choice that has to be made. Often accompanied by a vacant stare into the room.

Sitting on salt may have two fall-outs.
1) You may find a positive conclusion and end up "using the salt" for something useful,
2) You may come to a negative conclusion and end up throwing salt in your own wounds.

Sitting on salt about anything for a long period of time is disadvised.

Huh? Oh, sorry! I was just sitting on salt, I guess...
