GI

abbr: Genital Interface. Not currently implemented by video game manufacturers, but understandably the "next big thing" in console gaming hardware.

The GI on the XBOX 3 is customizable for length and girth and adjusts from 40-2000 Hz.

GI=GIRL INTRUDER

GI is a very large faggot who has a crew cut and a stick up his ass. You might see them traveling in packs because they are too afraid to fight by themselves they would cry like a lil baby and wet themselves.

when aproaching a GI be carfull to not wear any provocative clothing for this may trigger a reaction in the GI known as the "RAPE LOOK". If one receives the rape look run fo yo mo fuckin life.

Ways to identify possible GI, check for:
Dog tags
Crew cut hair
Camo clothing
Tight pants
Gay jokes
Country music
Brand new vehicles/crotch rockets
Cowboy hat
Out of state tags
Pockets full of rufies
Extreme psycotic rage
to avoid these GIRL INTUDERS.

Also all females under the age of 18 cary mase and a crew wit u at all times to avoid rapage.

GI

Literally stands for "Ground Infantryman", but many apply the acronym to the US Army soldier in general, whether they are in the infantry or not.

PVT Snuffy was an outstanding GI.
