I would have guessed that it meant something along the lines of localized (or one might say "loess-ized") mean +/- 2* similarly localized standard error of the estimate. To find out what the base R version of loess does consult `?predict.loess` and to find out what `geom_smooth` does, you can try to find documentation on the `predictdf` fucntion, but the geom_smooth help pages warns you it is undocumented.
