1. a term used to describe the act by which an individual swooshes freshly ejaculated cum in his or her mouth instead of spitting it out or swallowing it immediately after the life fluid has found its way into the speaking and sucking orafice (gargling is optional). The shockingly quick result of this mouthwashing method is the cum sticking to the inside of the aforementioned individual's mouth - most notably and annoyingly the gums - much like a delicious Devil Dog snack cake, though with decidedly evident deviations in both the overall experience and the cleaning protocols.
2. cum used in this fashion, namely as an impromptu mouthwash.
1. So I convinced the one over by the doorway to try a Devil Dog Mouthwash last night. She thoroughly enjoyed it...
2. Can I interest you in some Devil Dog Mouthwash?
