when it say for example refresh rate ~72Hz what does the ~ mean? surely not AC?

No, in that context, definately not AC

.

That symbol usually refers to a "complete oscillation".

Sorry, just edited my reply as I thought is was a bit brief

.

"complete oscillation" as in it will accept an input signal of 72Hz.

I don't really know what it stands for in every context, but I do know it's called a tilde

In an engineering context, tilde is often used as shorthand for 'approximately'.
