My current one is a South Park phrase used in an episode about Illegal Immigrants from the future. The rednecks would say:
"They took our jobs!"
Then, one would repeat it as so:
"Day turk uh Der!"
The latter is stuck in my head.
One phrase I had in my head a while back was, after doing a favor that was street wise, she replies:
"Ain't no thang, woo woo."
You?
