Have you ever heard of the word 'aggressivity'? Well neither had we until this morning's Dermot and Dave.

Dec & Doireann (who are covering on the show) were puzzled to hear Chelsea coach Maurizio Sarri use 'aggressivity' in his FA Cup post match interview last night. So they checked it out.

It's a noun meaning 'aggressive behaviour; aggression'. So now for ya! And there we all were laughing at Sarri.

Well this got the crew thinking - what words that aren't in the dictionary should be?

'Stalkward' and 'chairdrobe' kicked off a chain reaction of portmanteaus from listeners, who added the likes of 'internest', 'flatmosphere' and 'askhole', to name a few.

What would you add to the list?
