Twitter beef is the real deal, people come prepared and ready to fire back at any given moment. These interactions are such a crucial part of the Twitter experience, you will see people spend hours debating people on uninteresting topics.

The worst part about this is when some wannabe comedian tries to roast or debate actual comedians and they end up getting obliterated into oblivion.

Harry Potter author J.K. Rowling is also part of the Twitter community and when necessary, she does a great job delivering some ruthless comebacks. She's on fire and none of these trolls can ever stop her.
