The D.E.N.N.I.S. System

The D.E.N.N.I.S. system is revealed to be an acronym:
Demonstrate value
Engage physically
Nurture dependence
Neglect emotionally
Inspire hope
Separate entirely

Later we learn the M.A.C. system, the acronym:
Move in
After
Completion

And finally Frank’s system, SCRAPS!, which is not an acronym.
Frank’s system consists of flashing a wad of $100 bills and a magnum condom, to show you have money and a monster dong.
