A term to describe the phenomenon of finally finding something when you have given up on it. An example would be finding a girlfriend or boyfriend. If you simply stop looking so hard to find a relationship, eventually it will find you. The Lego Theory is based on what happens when you play with Legos. Typically while you are playing with Legos there is a moment when you are looking for a particular piece and can't find it. After you've given up on finding it and some time has passed, it magically appears.
