Oshite Mairu (押して参る) is often confused with Oshimai (お仕舞い). Oshite Mairu is humble language while Oshimai is polite language. Oshite Mairu is Adverb/Verb (Impertinently/Compulsively, Coming/Going/Advancing) while Oshimai is just a noun (the end, conclusion, done for, etc). Because of Oshite Mairu's difficult translation, and Oshimai's extremely easy translation, it is no wonder that they are easily mixed up and one is often favored over the other in English.

However, even an amateur can look at the kanji and tell that they are not related. Oshimai, by the way, used the kanji for Shi (from Kenshi, as in soldier, or Tenshi, as in angel [lit. Heavenly Servant]) and Mai, as in Dance. There is not much significance in the kanji choice, though, as it is likely a post-hoc rationalization: for some very old words which were created before kanji, they simply pick kanji with the syllable they want and the reading has no further meaning.
