The reasoning process (or lack of it) that causes ghetto folk to screw up their lives, due to their general ignorance and poor or non-existent judgment skills. Ghetto logic usually manifests itself in a series of successively worse decisions that often turn small problems into progressively larger ones, often to the point where solving the problem is beyond the control of anyone. Ghetto person then blames society/police/white folks/whatever for problems.
Ghetto Logic Example #1: Unmarried girl gets pregnant by accident, babydaddy runs off. Girl tries to catch a man to take care of her and her baby by getting pregnant again. Repeat process...
Example #2: Ghetto driver gets traffic ticket, but does not pay it or show up for court. Small fine becomes bigger fine, and arrest warrant is issued for Failure To Appear. Fine is not paid, driver keeps on driving, practicing same behavior that got him/her ticket in the first place. Police try to pull over driver again. Driver fails to yield, leads police on 100 MPH police chase, hits and kills innocent person. $50 infraction becomes no-bail felony manslaughter charge.
Same as hood logic.
Logic used by uneducated people when forming an argument. When someone takes two things that are not related in any way and tries to tie them together to make a point.
Reid: I know you are going to get drunk tonight cause your name is Ryan.
Ryan: Dude, I can't even argue with that fuckin ghetto logic.
