He: Ahm, dinner? No.I’ll have some snacks later.

-> As he is saying this, the camera focuses on the red bra. What he is saying: “Ich nasch lieber etwas” has two meanings:

a) what he is telling his girlfriend: Nah, I haven’t had dinner, I’ll just have a Snack (Naschen in the meaning of nibbling (? thats what the online dicitonary tells me, eating tidbits, sometimes secretly, “stealing” cookie dough for example)
b) what he is meaning with his utterance: Naschen in a sexual meaning, “vernaschen” or “naschen” as a ‘cute’ expression of having sex

I think through the video this ambiguity was obvious in some ways
