Flip Over Rule 

Similar to the 5 second rule, when reaching down to pick up an item of food that you dropped on the ground within the 5 second rule but fumble and flip the piece of food over onto the other side as to contaminate it more, regardless of the 5 second rule it is dubbed uneatable.

man 1: what happened to the last cookie?
man 2: i threw it out
man 1 : why?
man 2 because i was gonna eat it but dropped it on the floor then flipped it over trying to pick it back up.
man 1: gotta be careful, the flip over rule strikes again.

flip over 

during sex just before ejaculation the male extracts his penis, flips the female over and "finishes her off" anally.

Commonly used by men who are "still in the cupboard" (i.e. are gay but haven't come out yet)

1. Girl 1 "my boyfriend keeps flipping me over :("
Girl 2 "he's probably gay"

2. During intercourse
Male (extracts penis) "ok flip over"
Female "but I don't want to"

Flixover 

When you can’t stop watching the next episode of a series on Netflix you go to bed so late that you’re practically hungover at work the next morning.

“Dude you look fooked! Let me guess, another Flixover?”
