[Intimidator]

With a screen name of "Intimidator"?

I'm serious, I really want to know what a jackboot is? Got a picture?

[jackbill]

According to Merriam-Webster:

1 : a heavy military boot made of glossy black leather extending above the knee and worn especially during the 17th and 18th centuries

2 : the spirit or policy of militarism or totalitarianism

3 : a laceless military boot reaching to the calf

I believe that in modern times it refers to the Nazis.
