Haven't found what it means on any online dictionary but I did find other uses. There's a whole hashtag of it in twitter, it looks like.
For example, there's this one.
まずい聞こえたか。 恥ずかしい。 腰抜ける
To my knowledge, the first 2 would translate as "Did it sound bad? This is embarassing." No idea about the last one, though. 腰 and 抜ける seems to have a lot of possible meanings in the dictionary.
