What is Alternating Case? (Alternating Case Text Definition & Meaning)
Alternating Case (stylized as aLtErNaTiNg cAsE, SpongeBob Case, Mocking Case, or Sarcasm Caps) is a specialized typography format where characters alternate between small lowercase letters and capital uppercase letters throughout a word, sentence, or entire paragraph.
Under standard alternating case text definition, the first letter typically begins in lowercase, the second in uppercase, the third in lowercase, and so forth (e.g., "hElLo wOrLd"). In contemporary digital culture, the alternating case meaning conveys sarcasm, mockery, irony, or playful disrespect—frequently replicating the tone of repeating someone's words back to them in a mocking, singsong voice.
