Useless word of the day

Faire la bête à deux dos

 /fɛʁ la bɛt a dø do/
Fair lah bet ah duh dow

One of my favorites.
It literally means 'doing the double-backed beast'. I'll leave you some time to reflect on that. 
And this is how we part today.

Typically from a pulp detective story. 
'He thought she was vachement hot. The kind of girl with whom he would'nt mind to faire la bête à deux dos.'

Emphasis and enthousiasm (2)

Trop

/tʁo/ 
Trrow. With the rough french rr from the back of the throat. (Make sure you keep it dry, you don't want to sound disgusting)

Too much. Too many.
Slightly more intense and young than vachement. Emphasize the rr :tRRop 
'C'est trop bon.' It's so good.
Use with a verb :'I am trrop into Michel Houellbecq's movie art.'


  

Grave

 /ɡʁav/
Grr-ah-vuh. With a long a 'You say tomayto and I say tomahto', the second one.

It means stern, weighty, serious. Nothing to do with a sepulture. Definitely modern. Works with anything. Easily used alone, with an emphasis on the a. Grraaave, like a hearty 'totally', with a little head nod.
'Are you hungry ? Grave.'
This one is so short and efficient it could be american english ! It does carry something post teenage-ish that you need to take into account (don't you have the feeling that this hungry person is about to indulge in some unhealthy fast food junk ?). It is also grammatically incorrect of course as it is an adjective that tends to be used as an adverb.
Not for use in a grown-up/serious/in-laws/professional context.

Enthusiasm and emphasis (1)

La vache !

/la vaʃ/
Lah vasch

The cow ! is an interjection to express how impressed or how surprised you are. Don't ask me why. I have no clue.
 'Oh, la vache ! It's raining hard !'

 

Vachement

 /vaʃmɑ̃/

Vah-schuh-mah

Cow-ly ? The adverb made from cow. It means ' a lot'. It belongs to that nice homy slang you would let your child use in front of you, but not in a writen essay. To be used everywhere, in any situation from 'a vachement cold afternoon' to a 'vachement nice-looking neighbor', or even on its own.

'Did you like it ? Vachement.'
