look up any word, like blumpkin:
 
1.
The act of bringing your right fist into your left palm and, then, clasping them together close to one's chest, which makes a distinct slapping sound. This is most commonly done before the performer begins to tell an interesting story to his or her friends. The slapping sound also acts as a way to obtain the audience's full attention. Preambled fistclasps, for unknown reasons, usually occur when a male chooses to talk to his male friends about a female, or "bitch".
*preambled fistclasp* "So, dude, I was talking to this bitch..."

*preambled fistclasp* "Yo, broham, I ended up hooking up with that bitch last Saturday!"
