Like I can turn on/off a fake southern accent at will, but when I drink it naturally bleeds through at times. Less with the drawl like Zah's but more with my dialect such as words like "y'all" become rather frequent where as I typically try not to use it too often.
I know exactly what you are talking about Urial. I used to have a very thick southern accent/dialect. Then i joined the military and spent years in other places. My accent has very much died down a bit, but put me next to some people from my home state and holy ***you will lose track of what we are talking about in 5 seconds flat.
"Buckwheat, da hell ju think yer doin?!"
"Hey yall, aintcha seen this before?"
my famous last words are "Hey, Betcha cant do this"
