Be careful when you call out a geek for being a nerd, because chances are you're being totally offensive. The long battle between Geek vs Nerd still exists, and Rhett & Link go at each other in this rap battle to differentiate what geeks and nerds really are.
The duo drop lines like, "You're a geek, that just means you're a hipster wannabe" and "I was the cool form of uncool before uncool became a thing".
