[MACHO MAN]

Am i wrong ?

They are similar in meaning, true, but the F-phrase sends a stronger message.

Macho man, you do realize how incredibly rude and socially unacceptable your alternative is, right? You should never use this phrase outside of people you know very well and who you know will not be offended.

Unless giving offense is your intent. Or you don't care. Or you want to start a fight.

Go fly a kite.
Go tell your mother she wants you.

Both are rather benign expressions to say "leave me alone, you're boring or annoying me".

Go play in the traffic.
Go take a long walk off a short pier.

Basically the same as the first two, but somewhat stronger.

Your other alternative is as was already said rude, and generally not socially acceptable.
