1. dogs are barking
Translation: "My feet are tired."

I'm uncertain of its origin. I started hearing this phrase around 2002 or so from different people, then it was used by one of the soldiers in "Half Life: Opposing Force"

I originally took this to mean "I gotta take a DUMP!" But have been proven wrong , apparently. Nonetheless I still prefer my interpretation.
I gotta sit down...my dogs are barking!
