Top Definition
Theory of adult male/female interaction, detailed at intellectualwhores.com. States that men and women can never be friends unless the man is gay, is sober and finds the woman repulsive, or has another woman much higher on his ladder.
Trying to ladder-jump is extremely risky and should not be attempted by the faint of heart.

Ladder Theory defines the Kiss of Death: "I just want to be friends."
