Bepasikiškiakopūsteliaudamas (Lithuanian)

“While one was picking wood sorrel”, with “s” in the ending removed if “one” refers to a female, and with “s” if “one” refers to a male. Wood sorrel, actually, is literally referred to as “rabbit’s cabbage”. It is also the longest word in the Lithuanian language. Needless to say, it is rarely used.
