A girl from age 13-21 with blue jeans. The most offensive term ever. In 48 out of 50 states, it is illegal for boys to refer to girls with blue jeans as "blue Mustangs."

The boy equivalent is blue Camaro.
I love my blue Mustang, but I can't refer to my girlfriend with her blue jeans as one when she's around.
