As a saw moves back and forth through a tree, so does the penis move through the anus spraying debris. See anal shavings.
Last night when my boyfriend performed anal sex on me, my asshole underwent extreme friction causing the dreaded sawdust effect leaving flung skin and fecal matter everywhere. Damn, what a mess.

When you have a craving for cocaine but you know product quality is most likely going to be very poor.

Sawdust man is the most neutralest neutral. One of the more reconditrous members of Roblox's Cult of The Noobs. He enjoys gloves and his state of mind is always under a rock. Sawdust Man is uncultured and typically clueless of memes and generally what goes on in daily life. he also has problems misspelling things because yes. When Sawdust Man is sad he observes frogs extremely closely, and when satisfied with life he speaks word of the wise. Sawdust man is its own culture, but not completely yet defined. There has been a recent discovery about Sawdust Man's habit of misspelling: As we all know, Sawdust Man is made of sawdust. The sawdust of which he is composed of is godly, but also comes from trees that come from all over the world. This causes the tree spirits within his sawdust to mix together when he speaks, some in different languages. This is what is thought to cause his habit of what we like to call speaking Reconese, although it has yet to be confirmed.
Sawdust man is pretty rad. I heard he likes cookies. I also heard that he is the new leader of the hivemind!

When a penus (or finger) is going in and out of someone's anal cavity and the dingleberries go flying like sawdust.

The sawdust-like material accumulating at the bottom of the cereal bag. It is often poured on top of the last bowl of cereal, by accident, as you always forget it is going to be there. Cereal sawdust is not pleasant.
I woke up this morning and poured some cereal. Not much left in the box, just a few flakes and then a ton of cereal sawdust. I was pissed.
