I just learned the existence (and difference between) alphasyllabaries, abjad and abugida, and now I want to use this but I have no idea how, so I'll share it here.
If you're reading this you know how alphabets work:

You probably know how syllabaries work too (each sign being a syllable, like japanese kana):
> [ba][to][ma][no]
Now, an alphasyllabary is basically an alphabet where vowels are diacritics, ie small modifications (accents, dots, …) to the consonants:
> bªtmªn

An abjad (like arabic or hebrew) can be pure or vowelled. In a pure abjad, only the consonants are marked and the reader infers the vowels:
> btmn
A vowelled abjad looks a lot like an alphasyllabary, except there is a diacritic marking the absence of vowel:
> bªt⁰mªn⁰
Finally an abugida (like Ethiopian Geʽez) is a syllabary in which you add diacritics to change (or remove) the vowels. You can also think of it as an abjad with default vowels for each consonant:
> [ba][ta]⁰[ma][na]⁰

I'm not sure what you can do with this info, but I personnaly find it fascinating.
Anyway, after reading multiple Wikipedia articles, I finally stole the explications and examples from this excellent reddit thread about this meme you'll now be able to understand (if you were'nt already), and pedantically invalidate:
