'Goat fronting', that's what the pronunciation of the letter o in these parts is called. As in (does the sound) 'I don't know'.
A man from round here was up in court for having sex with a goat. He was spotted from a train by someone who rang the police. He denied all charges, but fibres of goat were found in his underpants.
More a case of goat-rearing than goat-fronting, to be pedantic, depending on how many ecstatic O's he gave vent to during the incident.
There is no animal-themed linguistic name for the other distinctive local vowel pronunciation, of the long i sound. As in the exchanging of palm-slaps while listening to a stereo in an apartment block: ah fahves to the ah-fah in the ah-rahse.
Except there is now because I've just invented one. Stoat-worrying. That's what it's called.
