1. Any material used to covertly clean up jizz. Bust napkins encompass everything from tissues to socks, and are frequently used when emergencies arise. Such emergencies include: having one's mother walk in, discreetly jerking off while one's roommate is asleep (those bathrooms are always so far away), and stealthily eradicating swimmers from one's bunk while in the Army.
2. The act of hastily covering up something.
3. An exclamation of excitement or awesomeness.
1. Sidney Crosby was receiving a facial from every employee of ESPN when he heard his boyfriend walking down the hallway. Realizing that he had little time to wipe off the bust and would be seen walking to the bathroom, he quickly used a bust napkin and successfully eliminated the bust.
2. "So, dude, what did you think of Nancy Pelosi's newest statement about waterboarding?"

3. "My new sound system is fucking bust napkins, bro!"
