Marmalade flapjack

Any unusual sexual act between two consenting young people that only occurs because they both know that they're not supposed to be sleeping together. A common euphemism that went around schools in southern England in the late 1980s.

"Tracey and that there Sandra did the marmalade flapjack in the bathroom at Wayne's party and they had to replace the shower head after."

"I didn't even really need a babysitter anymore, and I proved it when me and Julie ended up doing the marmalade flapjack on the stairs ten minutes before my mum and dad got home. She still got paid and all!"
