My favorite latin phrase is
“Cave Hominem unius libri” Beware the man of one book.
It means, “Watch out for dogmatic people.”
“Carpe diem”–Sieze the day
“Carpe cerevisi!”–Seize the beer! 
Omnia vincit Amor “Love conquers all.[sup]*[/sup]”—Virgil
*[sub]Sed amorem vincit allium. “But garlic conquers love.”—bibliophage[/sub]
I’ll have to second the Carpe Diem. Unless you’re my eccentric friend, who just loves Carpe Bussem, Seize the Bus :rolleyes:
good morning friends

I prefer…as Jay Sherman once said, “Carpe canem- seize the DOG?”
Or, in flagrante delicto 
i’m naughty, i’m naughty.
Cognito ergo spud - I think therefore I yam.
good morning again friends.
upon reading my post, i realized that i neglected to credit Henry Beard, the author of Latin for All Ocasions for the phrases in my post. i apologize.
“Cogito”, not “Cognito”, I believe.
Do I need more than one?
Personally, I think you are all mistaken in your picks. The actual best one is…
De gustibus non est disputandum
(There’s no arguing over taste)
Si hoc legere scis nimium eridutionis habes.
“If you can read this, you’re over-educated.”
It’s been a few years, but I’ll try to remember one we used in High School Latin I:
“Veni, Vidi, Wastamus gluteus maximus!”
Translated: “I came, I saw, I kicked butt!”
Carpe diem et memento mori
“Ubi, o ubi, est mea sub ubi?”
(Literal translation: “Where, oh where, is my underwear?”)
— Mr. King, my high school Latin teacher
Licetne nobis ad latrinam ere? (May I go to the bathroom?)
Ubi ignis est?
Oh and also:
Nunc est bibendi.
That was a Latin club phrase from my school, back in the day. Now is the time for drinking, or we must drink now…
Or, Bibo sum ergo. I drink therefore I am. I think I may have conjugated the first verb wrong. Eh, close enough.
And who can forget…
Cornelia puella Romana est…

idly wondering where Maeglin and LNO are at
Me, I like ‘Carne diem’. Meat day!
I’m gonna use ‘si hoc adfixum in obice legere potes, et liberaliter educatus et nimis propinquus ades’ as my bumper sticker.
