Get the Shiss Bomb mug.
A combination of Kung-fu, a Chinese martial art; and Confucius, a Chinese philosopher. It is a diss aimed toward fellow yellows to tell each other they have no skill. In rare occasions it expresses admiration toward one Asian and is used as a proper noun. It is pronounced with an Asian accent, while still keeping a gangster-ness to it. It is used most often within a crowd of Asians (AZN) or by a White person who has no clue what they're saying and thinks they're Asian and/or Black.
