My girlfriend is subtitling in a foreign language for an academic exercise and has come across two particular challenges relating to an episode of Gavin & Stacy. Neither of us have watched the series before and I am wondering if there are some inside jokes or themes or background prior to season 3 episode 6 that would give context. I'm a native English speaker who was born and grew up in the UK and I don't understand this.
In this particular episode (full transcript here) https://subsaga.com/bbc/comedy/gavin-and-stacey/series-3/episode-6.html
They find out they are having a baby.
0:17:43 I love you so much. I love you too, baby. BOTH: It's just the way it is. PHONE RINGS
What is the relevance/significance of them both simultaneously saying " It's just the way it is" at the same time? Is it a song with significance or a phrase relating to them discovering they are having a baby?
0:12:21 Hey, hot dog! Bryn burger! How you doing? Ohhh! Ho, ho, ho! And who's this little nugget? What a treat!
Personally I've never really heard nicknames like "hot dog", "burger" and "nugget". They obviously all have in common that they are food. Urban/slag dictionaries would have me believe
hot dog = cool (http://onlineslangdictionary.com/search/?q=hot+dog&sa=Search)
nugget = uncool/jerk/crazy: http://onlineslangdictionary.com/search/?q=nugget&sa=Search
Burger=someone who sucks at simple tasks. https://www.urbandictionary.com/define.php?term=Burger
Is there more to it than this? Personally I wouldn't have understood any of these nicknames.
