look up any word, like swoll:
 
1.
Slang term for modern United States military combat helmets. The "k" in "k pot" refers to either "kevlar" (the material it's made of) or "kraut" (for its resemblance to the World War II German Stahlhelm).

Another term for the helmets is "Fritz" helmet, again referring to its resemblance to WWII-era German helmets.
