Top Definition
A gesture in which is performed when one is excited, proud, or simply making an entrance. This action involves a thumb to the forehead with the pinky facing outwards as if to mimic a rhino horn. At the same time, the eyes are squinted, the chin is almost touching the chest, and the mouth should look like it is about to say, YEAH-YA, like lil' Jon would scream in his songs to show excitement. This position can be accompanied by the ass protruding out and the legs slighty bend. In addition, the beginning sound of the word YEAH-YA is made as if to whisper it loudly, making a hissing sound.

origin: In one of Dane Cook's comedy shows, he explains that he was watching two rhino's fucking each other on the discovery channel in slow motion and he could have sworn he saw the male rhino "raise the roof" as if to imply, "Hell yeah...I'm getting some!" To make Dane's imitation of the male rhino more realistic, he uses his microphone as a rhino horn and makes a facial expression, much like a guy would make to his buddy as he's fucking his girl. This whole gesture was taken to another level and is now used to express any kind of excitement, approval, or state of presence. For convenience, the hand to the forehead is used as a prop for the microphone or the actual rhino horn.
Chris: Guys, there's a Breaking Benjamin concert coming up real soon...
