v-twin 

V-twin is a type of motorcycle engine, featuring two cylinders, in the form of a V. V-twin engines are most well know for their use in Hardly-Ableson failbikes and Ducati and Buell wanna-be sportbikes. All engines of this type are characterized by a rumbling, glugging sound, with tones that create the impression of imminent disintegration. This is actually not uncommon. Other Characteristics of the V-Twin are incomplete and inefficient combustion, extremely low horsepower per cubic centimeter, high weight, and middle-aged-to older, often obese, riders. They are useful, however, in being the engine in the 2010 Buell Blast, the best V-twin ever. It also provides an engine for inline-4 engines to be much better than.

The new Buells look kinda like sportbikes, but they have V-twins too keep you from getting in trouble.

Wonder Twin

The Wonder Twin is a congratulatory sexual position involving two men and one woman.

Much like London Bridge move, the woman is on all fours, and the men are on opposite sides. The men touch fists like the Wonder Twins from The Super Friends and yell out "Wonder Twin powers, activate!" as their own form of congratulation to one another.

Chinese twin 

Your underprivileged, third-world doppelgänger.

I saw an armless, cracked-out man that looked like me in a gutter and couldn't help but wonder if he was my Chinese twin.

day after twin

n. Eddie Ramos. Day after twins may be good looking, intelligent human beings with a certain warmth to them that cannot be found in any other creatures. They are born the day after their "twin" and their twin may have many similarities.

"Damn, day after twin! You're one fine barista!"
