"gutsy" is an adjective to describe something brave, and sometimes foolish.
That was a gutsy thing to do - walking in front of the bull with a red handkerchief dangling out of your back pocket!
Macho describes someone overly masculine, someone with swagger and bravado. It is usually used as slang. "Macho Man" was a hit song - and describes the phrase perfectly.
Gutsy macho talk: "I could beat the tar out of you!"
" Go ahead. Make my day." (Clint Eastwood)
The "blues" is a type of music. It is always sad and speaks of losing a girlfriend, or having no money, and being lonely (often all of the above!)
I love this one by Chuck Berry. It is typical of the genre.
The country blues is the combination of the blues and country music. Nobody better than Johnny Cash - "Home of the Blues"
