1.)
Chicken Legs, aka Chicken Leg Syndrome, occurs when clueless
jock guys go the gym and train nothing but their upper body; arms, pecs, and shoulders, and they completely ignore their legs. They ignore their legs because they don't know how to workout, and because they think that girls will have sex with them if they have big arms.
They look out of proportion to the point of being a
joke, and it is officially called "Out of Symmetry."
2.) Meatheads who wont train their legs.
