So everyone has a different name for this type of Advance... here are the most common ones I have heard..

Grasshopper
Stack Loans
Stacking
Layering
Double dipping
2nd position

I was at a meeting this week and I heard this type of advance referred to by a name I have never heard before and I was literally on the floor laughing after I heard it

They referred to it as a "Doggystyle" deal

I am not sure if this name will catch on but it was very funny hearing it....
