This is my impression of a flatulent arachnid, or "spider fart" which if referenced by a woman in an old-timey southern mansion, might be pronounced as "spidah-faht". This seemingly odd spelling and like-wise pronunciation, perhaps worthy of explanation, would be on account of their ". . . Well known and often satirized dropping of "r's" in times when they precede another consonant or pause, which has the effect of elongating the pronounciation of the vowel before it. " as ray kooyenga explains it. Delving deeper, according to j. Fought who seems to agree, this was a originally a "southern english dialect associated with priveledge and prestigem" and in certain geographies of the southern and south eastern united states migrants "clung to such speech through its association with the influential proprietors of the southern plantation agricultural system. ". The use in "faht" has also another common southern linguistic trait of what the preceding gentleman might term a "confederate a". And so this, is the "spidah-faht" or "spider fart" if you prefer, as performed by ray anthony mimicking the fairly common species "arachnid flatulence gigantous".
