Slang term in which you turn "Root Beer" into an acronym "RB". This then stands for "random boner". It refers to when your sitting and out of nowhere, with no stimulus, you get wood.

Beer made from the ginger root (why it's also called ginger beer) and invented during Prohibition (why its called beer)

BTW, A&W is the only good root beer out there
