Animated cat from 60's cartoon, 'Top Cat'. Choo Choo is Top Cat's right hand man. Definitely the cutest cat of the gang. Never seen without his tight white shirt.
Top Cat: "Hey Choo Choo, do you ever take off that tight white shirt of yours?"
Choo Choo: "Nope. Eating breakfast = tight white shirt. Playing tennis = tight white shirt. Sleeping = tight white shirt. Having sex = tight white shirt."
Any person who has become so delusional about the supposed benefits of "rail" transit that they "have to have it", regardless of the excessive costs involved. Many Choo-Choo Buffs are more concerned about creating TOD (Transit Oriented Development) opportunities for their friends and political supporters than they are in actually providing the best transit system for commuters.
The only people insane enough to want to increase taxes to pay for a rail transit system are the Choo-Choo Buffs!
A choo-choo nigga is a group of dark skinned (ie. black) people who like to dance the conga in the street. Especially common in Palma de Mallorca, where daily choo-choo niggas walk the streets singing and dancing to their ryhtms.
This is the music prefered by choo-choo niggas "Choo-choo-choo, cummon and do the conga!",
When you begin by gently fisting your partner, imitating the connecting road of a steam train(link from the engine to the wheels). Slowly picking up speed much like a train itself. Once you have reached maximum speed you can manage, you yell CHOO CHOO, spouting two glorious arks of semen vertically in the air to mimic the puff of steam.
