The Panetonne is a sexual act which can only be done at Christmas time. It is when you tell your partner/lover to sit and close their eyes, as you get their Christmas present. As they are waiting you cum on there face
In the male (and possibly female) restrooms of high schools, cheap ceiling panels can be pushed aside. This allows students to climb up into the ceiling (usually by using the handles in the handi-capped stall) where they can smoke weed during lunch. Should not be attempted by students over 300 pounds.
"Dude! There's people in the ceiling!"
"Cracks in the ceiling panels, man. Cracks in the ceiling panels."
