Entry: iona (n.)
In context:"The sponsor, Ferocious Frnacis G., doesn't give Gately one iona of shit for feeling some negative feelings about it: on the contrary, he commends Gately for his candor in breaking down and crying like a baby and telling him about it early one A.M. over the pay phone, the sense of loss."
Definition: A neologism - either misspoke for "iota", or combining "iota" and "ion", I think.
