A grammatical error, such as the confounding of "it's" and "its", "you're" and "your", and "their" and "they're". Whereas a typo is a careless blunder caused by clumsy fingers, a grammo suggests a lack of understanding of the English language.
I hate when people try to pass off their grammos as typos.
