"A synonym is a word you use when you can't spell the other one" - Baltazar Gracian (1601 - 1658)

That's what a Thesaurus is for...
Oh, yes...and the Urban Dictionary if you want to stay current.

Of course, there is no other word that can match "f*ck" in syntax and expression.

And don't tell me you can't spell that... even if you're aren't allowed to say it!
