Translate that slangy sentence, please.
From the russian serial Fizruk, S1E1 around 12'50'':

Зай, ну харе там соплями мазать, иди потрещи. Саня. Ну?

If you can translate it in english or french, I just want to have an idea of what it means, Google Translate seems also a little lost :)

Answer

Hey, stop crying, come here. Let's talk. Sanya, come on...
There is a lot of slang in this dialog.
Something like that....

Answer

Соплями мазать is rough slang , some more soft in that meaning - ныть- , it is like sound that kids do when  they are complaining 
Трещать - to speak - is not so sped , but it  means to  discus about problems , not just to chat ,  another slang one - перетереть , But better to not use them at all
