When used in 1337 (leet), it is usually preceded by the article "t3h," meaning "the." The adjective "1337" attached to haxor (alternate h4x0|2, h4x0r, etc.) serves to magnify the amount of ass-kickage exponentially. Further, "t3h 1337 h4x0|2 #1" serves to signify that the speaker is claiming to be the dominant haxor, and that all other haxors are subservient to him. Further emphasis is added by placing a ridiculous amount of exclamation marks, numerical ones, and the word "one" after the phrase.
"3y3 4m t3h 1337 h4x0|2 #1!!!!!!!!1!!!!!!one!!!!!"
