Being on the same wavelength is similar to the expression "We're totally on the same page" or "Great minds think alike" It means that you and the other person are similar in thinking at that very precise moment. Often this happens when you voice a thought and someone else says the exact same thing or something similar. It just means you had the same opinion on something about a certain topic, issue or whatever.

Noun used to describe when you and your friend(s) are on your period and thinking the exact same thing, sometimes several times in succession.

It can also be used when not on one's menstruation, but that was not what the phrase was originally meant for.
