Rebekah Brooks told the Leveson Inquiry into press standards that David Cameron would sign his texts LOL, thinking it meant 'lots of love'.
Mrs Brooks said she later told him it actually means 'lough out loud,' after which the PM stopped using the signoff.

- BRB: Be right back
- LOL: Laugh out loud
- LOLZ: Lots of laughs
- OMG: Oh my God
- IBK: Idiot behind keyboard
- IDGI: I don't get it

- SMH: Shake my head
- KMT: Kiss my teeth
- IDR: I don't recall
