Don't tread on me!
From Wiki:
Gadsden flag Writing:
Don't tread-on me
Meaning or sounding like:
Don't threaten me
Translate "Snake" to Russian: Змея. In Russian "Snake" has another name: Гад (Gad). As we can see, "Gad" is a first part of name Gadsden (American general and statesman
Christopher Gadsden).
Gadsden = Gad's-den - name also sounds as Russian "Гад's день" - "Snake's day", which sounds as a proud statement. On the image, snake is ready to strike, in the first sign of danger. Message from Gadsden "don't threaten me" is played into message from heraldic snake "don't tread on me".
