Well... I see the Freudian association...

, but just from searching the net, it seems to me it is a used expression (what with 32,900 hits in Google...)
Here is a recent quotation,
"Want to see climate change? One volcano just blew its stack in Iceland, and caused havoc all over western Europe. There's another volcano in the same area that they're hoping won't blow its stack, too. And I have it from RELIABLE SOURCES that several other volcanoes will blow their stacks around the world in the coming years.
Oh, and there's going to be a comet or meteorite, too!" (unquote)
Crotalito, as for "i.e.", as said before i.e., it means "that is." from [<] Latin, id est.
Esto es: "Es decir" "a saber" "por ejemplo"
El Diccionario de Uso del Español de María Moliner te dice:
id est Expresión latina que significa «esto es» y que, escrita abreviadamente, «i. e.», se emplea a veces en escritos científicos o doctrinales.
