There's at least 5 girls you would have sex with in a room. Not date or take home to mom, just 5 girls that if it came down to it, or a lot of booze clouded your judgement, you would.
"Dude I walked into class and the 5 rule applies!" "Nice bra!"
The 5/24 rule refers to the principle of not giving head more than 5 times in a 24 hour period. Doing so may result in severe dry and/or sore throat if one is not accustomed to giving head regularly.
My throat is killing me after I broke the 5/24 rule yesterday!
