Pre-scran-scran

Pre-scran-scran is a meal eaten before the main meal. It might only be a snack, or it might be a more substantial.
Pre-scran-scran is by nature a savory meal and not a sweet like pre-scran-duff, or post-duff-duff

Pre-scran-scran in its most significant form could be an entire meal such as a box of chicken legs and fries eaten before your curry.
In a lesser form it could be a tube of pringles, some salsa and guacamole.

pre-scan 

A scanning technique in which the scanner performs backspoofing on a list of numbers to find out which ones have interesting CLID names. Telco test numbers will often have the name of the telco come up (ie. Verizon).

I did a pre-scan in 907 and found tons of test numbers from the Mukluk telephone company.
