Same here.
Hm. All I know is what I've learned from an ap, and they aren't really that practical. Here are a couple pickup lines that are just great.
At-il fait mal quand tu es tombé du ciel?
(Did it hurt when you fell from heaven?)
Tu es mannequin?
(Are you a model?)
(Not so much a pickup line, but i just like it
)
Voulez-vous danser avec moi?
(Do you want to dance with me?)
Here's a bunch of basic stuff you probably know already.
Non= no
Oui= he's
Déolé= sorry
D'accord= okay
Merci= thanks
Salut=bye, hello
Bienvenue= welcome
De rien= you're welcome
Bonjour= hello, good day
Bonsoir= good evening
Bon nuit= good night
Au revoir= goodbye
Sil te plaît (so much fun to say

)= please
