Text: Finer than a frog hair split four ways

Context: My informant said she heard this saying in rural Texas. She had asked a stranger how they were doing to which they responded “Honey, I’m finer than a frog hair split four ways.” She remembers the person being very upbeat and happy, and they seemed to be having a great day. My informant is from Austin, TX, and claims that she has never heard this saying other than this one time. 

Analysis: I am from Texas myself and have noticed that many Southerners, especially people from the rural south, use many sayings that add emphasis to their speech and attempt to capture the extent to which they mean what they are saying through exaggeration. Not only was this person fine, but they were finer than a frog hair split four ways. My initial reaction to hearing this saying was wondering “Do frogs even have hair?” A quick Google search has confirmed that frogs do not have hair. The comparison of how fine someone is to something so physically fine that it doesn’t even exist is a humorous, nonsensical way of suggesting that the person must be doing extremely fine. This saying exaggerates this even further by splitting the nonexistent thing into four different parts.
