look up any word, like bae:
 
1.
Rule of Five states that if you take five major porn categories, you won't find it in one single porn.
"What shelf can I find the Japanese Twin Stewardess Midget Redhead porn?"

'None--It doesn't exist. Rule of Five. Try Clown MILF Foot-worship Outdoor porn instead."
