- (panicked yell) FUCK !!!!!!
- Naaah, je déconne :-D !

To fuck around :

- Yeah ... about Scott ... he's been dicking around for 15 years = ça fait quinze ans qu'il passe son temps à déconner ... Maybe that would not hurt him to get a bit serious, for a change !

To be fucked up :

- Hey, Matt, heard about the latest decision of the Supreme Court ? They ruled that a Corporation is a person with freedom of speach, and therefore should be OK'd to donate to an electoral campaign.

(alternative) :

- Putain de bordel de connerie d'écran de MERDE !!
