English to Dutch Other Other Uitdrukking in slang

Hi everyone, I am currently subtitling a series containing lots of American slang idioms (NY slang), such as 'eat someone's face'. Here's some context:

Don't you guys hate it when you first
start crushin' on somebody,
and then all you wanna do is just
fucking eat their face?
As in aggressively eat their face.

This can be 'Passionate kissing (intens kussen)', so a compliment to someone, but can also be seen as a threat (urban dictionary). There's drugs all over the place, so the expression could be linked to bath salt users, a drug which apparently makes people 'eat faces'. This is some weird stuff indeed.

Maybe someone else can shed some light on this. Would be well appreciated.

Thank you.
