Definition of "missus"

Sometimes I find myself sitting back and reminiscing / Especially when I have to watch other people kissing / And I remember when you started calling me your missus / All the play fighting, all the flirtatious disses

2006, “Littlest Things”, in Alright, Still, performed by Lily Allen

Imagine you have driven past a restaurant and thought to yourself, 'That would be a nice place to take the missus for an evening out,' and in no time at all you have found yourself flicking through the Yellow Pages in search of the phonenumber.
