We're 99% sure Chloe Grace Moretz just invented the term 'swacket' but then we too are also not 19-years-old and, by her insult logic, suffer from 'old brain'.

Seth Rogen and Moretz sat down for a radio-friendly insult showdown for BBC Radio 1 and ended up throwing far more dirt at each other than we thought was allowed on daytime radio. 

If this is what they get up to on a PG rating, we might actually start looking forward to 'Bad Neighbours 2'.
