What's the SpongeBob case meme?

aLtErNaTiNg CaPs, originating from a SpongeBob SquarePants episode where characters mocked each other. Used online to mock quoted text.

Does every character alternate?

Only letters — digits, punctuation, and spaces pass through unchanged. 'Hello World' becomes 'hElLo WoRlD'.

Toggle — default starts uppercase on first letter. Reverse the pattern if the meme calls for it.

No — screen readers may spell out each letter individually because capitalization changes suggest acronyms. Use sparingly.
