These terms may have been restricted to only So. California.
After World War 2, and extending through the Korean War, there was massive home construction developments in the So. Cal. area. The demand for homes by the returning veterans, and the financing by the GI Bill, fueled the home building industry.
Tracts of 300 units were average size developments.
These homes were in the median range of 1200 square feet. Sale prices were about nine dollars per square foot.
The total cost to wire these was about $250. per unit.
These homes were called "dingbats" by the wireman, the wireman were known as "dingbatters". Now the wireman are called the more dignified term "Residential wireman".
There was fierce competition among the dingbatters. Union scale was about $1.75 to $3.30 per hour, during this era.
I once contracted for rough in, labor only, on a 300 unit project. I set a record by roughing in, including hanging a 60 amp service, of 90 units in 90 days. I received the huge price of $50.00 per unit.
Considering that I purchased a new Ford pickup for $1950.00, this was big money.
