One of the initial examples http://lolcode.com/examples/gimmeh suggest GIMMEH as the function to read from STDIO. Personally I think “give me” suggests too much grammatically sophistication. GIEF would be a better and clearer choice. It is more direct, implies less sophisticated use of grammatical cases, it's simpler to code and most importantly is more amusing.
