Five second rule 

The rule that states if a guy is in and out of a girl's vagina (and finishes) while having sex in five seconds or less, it doesn't count toward his body count.

These girls should call me the delivery guy with how often I enforce the five second rule.

3 second rule 

Originally used in basketball, often termed as lane violation.

For modern day use, it's for when you drop your food on the ground, but you say " 3 second rule!" as an excuse to say that your food remained clean.

"Yo hand me that juicy barbeque bacon burger"
"There you go bro.. *OH SHIT I DROPPED IT*"
"Pick that shit up, 3 second rule you remember?"

the 5 second rule 

the 5 second rule isn't even true like the food when you drop it the bacterias get on it under literally one second

You: did you try to just catch your food under 5 seconds because the 5 second rule is not true
Friend: yea?
You: because if you even drop your food the bacterias get on it in under one second even if you wipe it

3 Second Weed Rule 

Hold your pot smoke for 3 seconds and exhale, because science bitches. According to Steve Liebke’s 2001 ‘A Cannabis User’s Harm Reduction Handbook,’ “Take small, shallow tokes or pulls. About 95% of THC in cannabis smoke is absorbed in the first few seconds so breath holding is quite pointless. All it really achieves is a far greater amount of tar being deposited in the lungs.”

Dude puff pass pass, your harshing the 3 Second Weed Rule noobie.
