Another way to rank hot or not women building off the 5 second rule for leaving something desireable out before it gets germs on it. If I leave you a woman alone for 40 seconds (e.g. to go to the boys room), then if she is a hottie you'll have to insert yourself into a conversation between her and another guy when you return cause 40 seconds has gone by and someone is already hitting on her, i.e. she picked up dirt.
My date was okay but she didn't meet the 40 second rule at the bar.

The 10 Seconds Rule is a great way to take wicked pictures.

Common things to do are too pick someone up, get naked or doing a handstand, or all above.

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.”
