When to Use Inverted & Alternating Case?
Inverted case (tOGGLE cASE) is a handy corrective tool when you accidentally type an entire paragraph with Caps Lock turned on while holding the Shift key for capital letters (resulting in hELLO wORLD).
Alternating case (aLtErNaTiNg cAsE) became a viral internet phenomenon in 2017 with the popular "Mocking Spongebob" meme. It is widely used across Twitter/X, Reddit, TikTok, and Discord comments to convey a mocking, sarcastic, or mocking repetition tone without needing to write out "sarcasm tags" like /s.
