The process of liquids (such as semen) becoming a semi-solid or solid state from the contact of water or other viscuous substances.
When that girl sucks on my dick in the shower my semen went through this wild coagulation and became small chunks all over the place. She ate them.

The act of getting a notoriously big dick. Not for the faint of heart. Most commonly performed by ninjas and physicists.
If coagulation lasts longer than four hours, consult a physician immediately.
