English                                                    German
Hi, How are you?                                      Hi, Wie gehts dir?
I'm fine, what about you?                          Mir geht gut, und dir?
Can you please help me?                            Könnten Sie bitte mir helfen?
Thank you!                                              Dankeschön!

I would like that, please.                            Ich würde gern das bitte.
This one or that one?                                Dieses oder das?
Yes that one.                                          Ja, richtig das.
I love you!                                              Ich liebe dich!
I don't love you!                                   Ich liebe dich nicht!
WOW, AWESOME!!                                    WOW, TOLL!
SEXY! or COOL!                                        Geil!

That's all what i can think of right now, maybe i'll add more later. if you have any question, post it!
Don't bother using Google. it translates words, not expressions, and it has many Errors when it comes to German.
