Tefillin Date 

When a religious Jewish guy brings his tefillin (phylacteries, a Jewish prayer accessory) on a date because he expects to be spending the night at the girl's place and he'll need the tefillin to pray in the morning. It is an indication that he's religious enough that he needs to pray every morning with the tefillin, but not so religious that he won't have sex.
Shlomo had a tefillin date with Tzippi last night. I saw the bag sitting on the table at Estihana and then I saw him in the same clothing at Shacharis in the Jewish Center this morning.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
