Thats a fun show I've just listened to it and will listen to the rest of the series.
Stephen didn't mention penis's (Phil Wang made a far less subtle reference right near the start of the show) at all.
Susie Dent (I think, well it wasn't Lucy Beaumont and there were no other women on the show) suggested a new word 'licksation' or 'lixation' theres no info on how it would be spelled... to describe the situation when you've got an icecream and someone wants a taste of it, they have a 'lixation' .. a fixation on licking your icecream.
Stephen asked: "could this be applied to anything else?'
Thats it. Yes, of course the innuendo is there but it's supplied by your mind, he could have been referring to Lollipops or icelollies or any number of other things.
He didn't make it personal, he didn't suggested he had a lixation towards Susie Dent or anything she might have, it wasn't a whispered thing in an empty green room or as he brushed his genitals unnecessarily up against someones bottom 'in passing'...
And really quite crucially it was on a show about words and their meanings, use and creation, hosted by Susie Dent and Phil Wang.
Absolutely fucking worlds apart from Ggreg saying to Katy Brand that he'd 'love to munch the living daylights out of your.... little tart'.
I was more surprised that the word 'twat' was acceptable pre watershed Radio4 language (Phil Wang).
