2 1/2

2 1/2 was created by a kid in 2005 at Creekwood Middle School. Many have asked what 2 1/2 is, but the true responce is "Only the special may comprehend the power of
2 1/2." Only the creator can choose who the special is, and the "power of 2 1/2" means 2 1/2 is very powerful.

2 1/2 is the most powerful number, so only a few can even comprehend it.

2 & 1/2 week rule

The aproximate amount of time since last time you had sex/intimacy with someone; when you are the most in danger of doing something stupid just because it's been a while since last time you got any.
Often involves going back to previous partners.

If you get over the 2 & 1/2 week rule phase, your next sexual encounter is much less likely to be looked upon as unfortunate.
