D.E.N.N.I.S System 

The D.E.N.N.I.S. system refers to a fool proof system enabling men to obtain a woman's undying love, accompanied by life love devotion (if the man so desires). The D.E.N.N.I.S. system was made popular by Dennis Reynolds, a fictional character from Its Always Sunny In Philadelphia. The system, although original in name, is similar to "The Effect," which also goes by the separate name "DJGorbeism," popularized by D.J.G. When one engages in "the effect" they are "IN EFFECT."

D- Demonstrate Value
E- Engage Physically
N- Nurture Dependence
N- Neglect Emotionally
I- Inspire Hope
S- Separate Entirely

The way to win any girl's heart.

Example of the D.E.N.N.I.S System/In Effect

Kalie, "Hey this is some good pizza."
Dennis, "You're the one that is good."
