I like new modern words and phrases, created for comedic value. The late, great Douglas Adams created a book full in The Meaning of Liff. The rude one from Viz is good too. In that same tradition Charlie Brooker has added some here. My favourite amongst his selection is this:
piersonality (peers-on-allitee) n. Self-consciously odious celebrity who trades on their own widely accepted repugnance to infuriatingly lucrative effect, thereby creating an unassailable feedback loop of violent loathing in absolutely everyone other than themselves; eg: Piers Morgan.
