live love laugh
A sign put up in someone's house meaning you should leave the premises and cut off all connections with the owner never to return to that place again.
Example:
I moved into my new flat and saw my flatmate had a 'live love laugh' sign up in their room so I had to sleep on the streets that night instead.
