- French is my primary language -

I was listening to one of my favorite movies, The 40-Year-Old Virgin, and one of the characters said something I didn't understand.
Andy was seducing a woman in the library and she found him very attractive. After a few sentences, the woman said : "Don't tell on me, Andy..."

What does it mean ?
In this context: don't tell other people about our affair. Another example:
Thieves rarely tell on each other.
= Thieves rarely report other thieves' actions to the police.

andy was all with the bullshit that he was doing,so when that girl said something he replied shit i didnt no there was a problem
