Culture in the classroom-Phrase of the week

One of the things that I am going to make darn sure I do this year is be consistent with my phrase of the week. Last year, it was something that worked really well. I spent maybe a minute once a week on it, and it magically appeared in my students' vocabularies.

My sister is home from a year abroad to renew her Visa, so I was asking her for some common phrases that are being used in France right now. Here are some phrases that she told me that you might want to use in your classroom (if you teach French, that is) I don't have accents on this computer, so you'll have to add your own...

fais gaffe: watch yourself
tu pues comme un ours: you smell like a bear (my kids LOVE this one)
Ca m'est egal: I don't care
fais attention: pay attention
franchement/vachement: frankly/really really
c'est chaud: that's rough, that sucks
tant pis: too bad
et alors...: so?
Ca tue/c'est mortelle: that's killer, that rocks
Tu es tres charmant(e): a compliment for the opposite sex, usually used for the ladies
supercanon: hot lady/bombshell
je suis a fond: I'm excited
j'ai le beguin pour: I have a crush on
degun: personne
se bouffer: to eat
un gar/un mec: dude
une nana: a chick
ca craint: that sucks
t'es nul: you suck (of course, you would use this with caution...)
a plus dans le bus: see you later alligator
a la prochaine dans le train: after a while crocodile
il est a fond la caisse: he's into that
cingle (accent aigu) d'elle: crazy about her
fetard: partyer
bosseur: worker

I'm also going to try to come up with some natural subjunctive phrases to use in my stories. So far, I have (of course I can change the subject):

Il faut qu'on fasse
Il faut que j'aille

If you have any that you think are pretty common, let me know! I haven't taught subjunctive ever and haven't really used it since college, since I only teach first year. Help a sister out!
