Grammar Cringe
When you see grammatical errors in a post and can't do anything to fix it. The cringe is worse if it is someone you respect or would feel bad to correct, or something that you like or agree with. It's like a booger hanging out of your best friend's nose but not being able to let them know.
I couldn't help but grammar cringe after reading my English teacher's post about her grandmother dying, because it had so many misspelled words and improper punctuation.
