I can't stand people who abuse expressions.
"I could care less!" You dumbass. That means you have some level of 'care' in you. Because you CAN care less. The correct expression is: "I couldn't care less!". Do you see how much sense that makes? A lot.
Also, in another thread someone said something 'peaked their interest'. It's piqued. Something piqued your interest.
In my opinion, if you don't have dyslexia and English is your primary language, you have no excuse to misspell things.
But I am a grammar Nazi.
