What are those "chunky" things around your lips?

If you kinda bite down below bottom your lip you'll feel a buncha little tapioca-like things. What are they?

Do you mean the small "lumps" under the skin, giving the tissue inside your lips a sort of grainy texture? That's just connective tissue, muscle, and some blood vessels.

**edit**: and glands, as others have correctly pointed out.

If, however, you have external expression of these bumps you describe, you should have that looked at.
