Fa Do Sol Ré La Mi Si
(F....C....G....D...A...E...B)
this is the order in which sharps go. Gives you the tonality of a given song. Let's say the song takes 4 sharps- take the last one (Ré/D), add a half-tone to it (Mi/E), there it is, your song is in E major
It works with flats as well, in the reverse order (Si Mi La Ré Sol Do Fa). Take the next-to-last flat, that is your tonality.
That's cool!
I don't understand any of it. (ELI5 please? Thanks for sharing this anyway!)

It's helpful if given a partition (with sharps or flats duly noted in the key signature), of which you want to quickly know the key -thus the tonic chord, usually the one any given song begins and ends with... broadly speaking. With this mnemonic you can immediately tell what the key is and start playing. Of course most people who play an instrument have developed their ear so that they can find the key of most songs they hear intuitively/empirically, the trick is useful with a partition only.
