- (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.
- Putain, ils déconnent sec, ceux-là !

(alternative) :

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
