happy chain 

A chain to which a new link is added daily, and onto each link the happiest part of the day is written upon in any form at all. Fragments, sentences, pictures, doodles, whatever.

Look back on it. It reminds you of the happy memories you've had. It's marvelous.

Last Tuesday made for the most explosive happy chain link ever!

Chain Happy Ending 

1. When a Chain Reaction ends up positive instead of negative.
2. When one person has sex, is more confident because of it, who motivates someone else to have sex with them, who in turn is more confident, rinse, lather, repeat.

1. So, I got held up in a class, but it let me stay with this cute girl, which allowed me to get her number.
2. Me sleeping with Brenda allowed her to have a Chain Happy Ending. Aren't I the best?
