Its not perfect, but the best translation I could do: S she; H he; P policeman
S ..we'll stew here until we're black, this fucked-up little rat. But not with me. At some point it's over (staring at the cake) H Do not dare! (because he made the cake to please her) S Lick me! (leck mich" is literally lick me", but means also something like fuck you!") H (something like): you horny bitch! S I said lick me! Lick me! Lick me, what are you waiting for, a written invitation? P Excuse the disturbance, I don't want to interrupt the meeting, but [name] informs us that the budget negotiation has to be postponed, she is busy elsewhere. H So? ok? S And with what, if I may ask? P We found a frozen corpse in the river. I'm just on my way there. H Then tell her to suggest new dates for us! S But if possible still next week for a prompt solution! P Allright, I'll tell her Is this Topfenschnitte? (kind of a cake) H Yeah, sure! P Isn't it too geil? (geil" is a very fat cream or to be horny) S Oh no, we find it very delicious H Yeah, the cream is almost sugar-free, also the fruit topping. And then I use a very light shortcrust pastry base, you know? P Allright! Thanks for the tip. Have to try it with [name] sometime. H Yes, absolutely! I'll email you the recipe straight away! (grabs his phone) S Aaaahhh!!! P Very nice, thanks! See you! S ..
