For me its worse,
I can do almost any accent, very few that i can't,
A lot of times i do them for fun, then can't get them to go away for atleast 10 minutes
Whenever i am with someone with an accent, say a Mexican accent, which means half my school, i start talking with that accent and can't get it away
Hey man WAS UP? OHH NO HOMBRE I DIDN DO DAT SHET! Then i realize what i just said and i sit there like
O.o WTF?
