What's a Radler ?

In Germany, I drank a Radler, although I thought everyone was saying "Rattler"

What is a Radler?
A beverage that is a half-and-half mix of blond lager (usually Pils or Helles) and lemonade. This drink originated in Bavaria in the early 20th century.

I think Leinenkugels - Summer Shandy taste a lot like a Radler/Rattler
