Please help me with this word.
I can imagine a general meaning that 'it is not good'.
Thanks.
The definition I saw
http://dictionary.goo.ne.jp/leaf/jn/225949/m0u/%E3%81%B1%E3%81%A4/
seems to suggest it's more a bit more superlative than 'busy' or 'tight'. Maybe ''with utmost effort', 'intensely busy' or 'bursting at the seams.'
