1. When something in reality causes someone to remember/think about a moment/event in the TV show 'Scrubs'.
2. When someone zones out, tilting their head to the right slightly and pointing their eyes up and to the left - like the character John Dorian in the TV show 'Scrubs'.
Person 1 is talking about their friend who is inseperable from their partner. Person 2 then instantly goes off into a daydream thinking that the couple is like Turk and Carla from Scrubs and remembers the episode where they are depicted as a two-headed being.
This would then be followed by Person 2 saying "I just had a Scrubs moment!" and they would describe their thoughts to Person 1.
