Satan's Mouthwash 

The rare term of describing how it feels to temporarily choke on your own spit mid sentence, usually some people use this term in an angry, annoyed way (In an irrational tone of voice)

Random Guy: "Steve, this morning I just got Satan's Mouthwash 3 times!"
Other Random Guy: "That sounds horrible, Alan."
