You are reading rather useless literature, Mohammad.

grotesque(i want to know it is formal?) -- none of this stuff is formal, Mohammad; it is all street slang. 'Grotesque' has a more formal usage, but here it means 'unattractive', 'repellent'.

break sth to sb(i know without context it is difficult) -- give information to someone that will be emotionally difficult for that person to learn

Quit reading this trash, Mohammad, and find yourself a decent piece of literature if you wish to learn the language. Few of these phrases will be used by anyone you wish to meet, and most of them will quickly disappear from the language. They are slang of the moment only.
