Italian phrase meaning "be quiet", "be cool", "don't be a pain in the ass". Literally it could be translated as "stay dick", which doesn't make any sense in Italian as well.

Even in its plural form, "cazzo" must be used in the singular.
"Stai cazzo, I'm sick of your bullshit".
"Everybody stay cazzo".
"State tutti molto cazzo".
