An Asian man who dates outside of his race and often converts women into being attracted to Asians. For example, a Gateway Asian will often hear “you’re the first Asian guy I’ve ever been with.”

This is typically a male because Asian men generally don’t have a lot of attention from non-Asian women.
“Notice how Vince tends to attract chicks who have never dated an Asian before? How’d he breakthrough?”

“Dude, I thought you knew. He’s a freaking Gateway Asian. If they don’t work out, her next boyfriend will probably be Asian too.”

Get the Gateway Asian mug.
in reference to an unsuspecting asian person (esp. a tool), used by a non-asian solely as a way to meet other asians and to infiltrate their culture.
1) That American girl has never met an asian guy before. So she befriends the naive Takeshi -- her gateway asian. Now that she is comfortable with being around Japanese people and is seen by enough of his countrymen, she abandons Takeshi, eats a lot of sushi, and sleeps with hot asian guys.

2) Japanese kid (to an American girl): stay the fuck away from me. I'm not your gateway asian.
