Actually you can find some of -る動詞 100 years ago like サボる originally from sabotage (French) る around 1920 years.
Now we have so many -る動詞 we don't even know when it originally came from but ディスる has been on the internet since early in 2000.
Here are some of -る動詞 I've been using since I was a kid in 1980 - 1990s.
