Is it cyberbullying or not?

How can we differenciate cyberbullying from others types?

One of the main characteristics to be cyberbullying is that there must be under-ages in both sides. If there are adults, although it's also through the social media, it's another type of cyberbullying, like sexting.
The meetings out of the social media like sexual abuses, are not cataloged as cyberbullying as it's proper name says cyber, which means through internet.
