rice steamer 

A (almost always) white guy that dates asian women. They are stereotypically effeminate and go for them so they can feel manly compared to their slim physiques and thigh pussies(for obvious reasons), and/or far-rightists that reject white women on the grounds that they aren't traditional and "burn the coal" and cheat, while asian women are more submissive.

Analogous to coal burner and oil driller

Steamed Rice 

Newbie

In Korean, "steamed rice" is slang for "Newbie". It evolves into the sentence "You are my steamed rice", which simply means "I own you". Popular during Starcraft ceremonies when the winner throws a bowl of steamed rice towards the direction of the loser of the match(s).
