Weird sayings/Inside jokes

Does your family have any inside jokes/weird sayings that other people wouldn't understand at all?

We call the remote the 'oofadofa' in our family. I always get embarrassed when I accidently say it infront of anyone else.

Inside jokes - One time at my grandparents with all my family there, my sister and I had to share the double bed so everyone could fit in and stay over, as we were going to bed randomly my Nanna blurted out 'no touchy feely' So now whenever anyone stays over at my Dads or Grandparents we all say no touchy feely before anyone goes to bed. It would sound so weird to anyone just hearing that not knowing why.
