Have you heard that kid talk?
Yeah, its terrible his grammar is so bad I can't understand a thing he's saying. Its like language-rape.
Language rape is the mis-spelling of phrases or usage of incorrect grammar that is so bad that it can be considered to be a form of violation of said language. The phrase may be used in a variety of contexts, such as a facebook post that is unreadable or even the deliberate warping of language for political purposes, most notably the feminist inventions: "womyn", "wimmin" e.t.c.
Raving feminist: "womyn have been oppressed for so many years, but things will change!"
Joe Public: "I know you were raped as a child, explaining your hatred of men, but does that mean you have to commit language-rape in revenge?"
When travelling/studying in a foreign country, people from that country come up to you to speak your language usually merely for the sake of showing off their language skills to you or for practicing.
We were walking down the street in China when this guy came up and started telling us all about China in broken English.
