What does it mean?

腰を抜かす.

Although i can find the meanings of all the words in this sentence, i still couldn't understand the meaning. My dictionary says nukasu is to leave out and koshi is to hip.. Any help?

where did you find this?

I found similar pharses with two kanji that looks similar to the one you have up.
腰を据える 【こしをすえる】 (exp) to settle oneself (in a place)

腰を掛ける 【こしをかける】 (exp) to sit down

腰を抜かす【こしをぬかす】be unable to stand up
It is also the idiom which means "be very surprised".

hi!

does that translate from english to japanese? i have tried all the usual free online auto- translation sites, but which do you all think is the most accurate (i know they all tend to be pretty bad sometimes!)? i have also been looking for a translator that translates romaji into english, does anyone know of something like that? i'm looking for something to make IMs easier for me and my penpal -- we take our time in emails to each work on our language skills (me on japanese, him on english), and we study on our own, but sometimes we just wanna chat nice & relaxed, and so we both use auto translate sites sometimes. but...as you must all know, sometimes they can screw things up pretty badly, and we are both beginners in each others language, so a fun chat can turn stressful now and then, and a simple sentence can sometimes take like 10 minutes to communicate (a good joke can really lose its punch that way! xD ). i'd appreciate any help!

This site translates romaji to English and English to romaji:

thank you, so far that's very helpful for romaji!
