The internet phrase "This is me giving a fuck", usually with a picture of a person not interested in something.

So, when you look like you're not interested in something, you're actually interested?

I never understood the saying "Tea calling the kettle black" or something like that. Just...what?

The phrase is "The pot calling the kettle black", and it comes from a time when wrought iron was used to make (among other things) tea kettles and cook pots. The phrase is a way of saying that someone is being hypocritical.
Glenn Beck saying that Charlie Sheen is crazy would be an example of the 'Pot calling the Kettle black'.
Another example would be a Klansmen saying that a Black Panther was a dangerous, racist extremist.

"That's your opinion" drives me nuts of course it's my opinion.

It's also another way of saying 'I disagree'.

Tit for tat. I know what a tit is, but wtf is a tat?

It's a reference to trading - literally 'this' for 'that'.

I never quite got the phrase Thick as Two Short Planks.

It means to be stupid, but why two short planks? The planks is the length so important?
