Hi all.
I'm not sure whether this is an idiom or not, but I hear people say it a lot.
'sick to one's stomach'
It means likely to throw up or feeling very upset.
Here are some idioms about 'butt'
'bust one's butt'
It means to make an extreme strenuous effort to exert oneself. (quote from the following thread)

'shoot yourself in the butt' (another variation of shoot yourself in the foot)
it means to unintentionally do something which spoils a situation for yourself.
