put my foot down 

to tell someone in a strong way that they must do something or that they must stop doing something. You can't just let him do what he wants, you'll have to put your foot down.

upside down pineapple 

The pineapple represents hospitality and welcoming. A pineapple is placed on a porch or mail box by swingers to signify that a swinger party is going on. A pineapple is turned upside down when a person is in search of a swinger party. Originally it was turned up side down in the individuals shopping cart. But pineapple popularity has made it accepts on clothes and other items. Swingers use this symbol to identify each other in public.

My neighbor left an upside down pineapple on my porch last night. I think he wants to swing.
