The "Shift" is when a guy (sometimes a gal) goes from DFS to DFL. Sometimes it happens because he has been dating seriously and sees the long-term potential or possibly has experienced lovematism. Sometimes it happens because he is bored with superficial one-night-stands or FWB and wants to settle down with one woman.
