Samsung's Bixby delivers a scorching hot rap burn on Siri ... if you know how to ask it

The fight between Samsung's built-in AI assistant Bixby and Apple's Siri just escalated to a full on rap beef.

Aside from one-upping Siri's assistant capabilities (Bixby goes beyond simply answering questions and can assist users in all sorts of phone functionality), Samsung's AI also delivers some secret jabs at Siri ... if you know how to ask for them.

After Samsung rolled out Bixby to Galaxy S8 and S8 Plus devices in South Korea this week, several users noticed the hidden insult could be accessed by asking Bixby to "please rap."
