A student club in which each morning before school, a group of three students drink in the parking lot. One drives to pick the others up, at 7:15, and 7:20 respectively, hence the 15-20 name. There are 3 rules: 1) Keep it down! 2) The three Founding Fathers only may share the booze, guests are BYOB 3) No over-the-top douchebaggery while in school.

The date in which two people had officially became life long partners.

The two pieces became aligned and vowed unity together to create the most beautiful and aesthetic team.

Bad thing is these two's communication and attitudes. The couple are each other future husband and wife. They have a long journey ahead of them but, it is only based upon the how much they will stick together and ride out anything that is thrown at them. Like in the Bad Boys series, they share an u breakable bond and are always going to make it all work and bring down the bust they are on. Sometimes their personalities clash even though they are so much alike.

If a unity was ever made on this day, they are simply soulmates and will be together for the rest of their lives. Committed and loyal these two will never have to worry about losing one another as long as they are by each others side.
Only down fall is if one becomes unfaithful, cheats, or gives up on their energy transfer. One may not make it after this. They are strong as a whole but, become lost and weak alone. This usually causes one to become volatile and corrupted whilst the other becomes hopeless and unfortunately commits suicide. It's very important for these two to not give up on one another for they have a future of fruitful treasures ahead of them.
