Retard Unit
when a lot of retards get together and start thier own unit. most of them need wheelchairs or zimmer frames to move.  they can use thier walking sticks as shotgun when anouther unit drives up on thier turf.  the reatrd unit often perform drive-bys on thier wheel chairs, and some times have drag races in thier wheel chairs modded with nitrous oxided that can get up to speeds of 150 mph.
wow look at the retard unit they can bearly walk but they sure can fight.
