Isn't "fuch" just a misread or misspelled "such"? "Such" makes sense in these examples!
I mean what on earth is "fmoke?!!! (in the last line of example 3)This has to be "smoke"! I checked "fmoke" in wordnik and as far as I can see, all the "fmoke"s can be replaced by "smoke"! I'm just saying, check the reference again and use your common sense!!
