- Harry Potter: "Good – well, look, Neville, we've got to be somewhere, we'll see you later –"
- Neville Longbottom: "Don't leave me! I don't want to stay here alone, the Bloody Baron's been past twice already."
- Ron Weasley: "If either of you get us caught, I'll never rest until I've learned that Curse of the Bogies Quirrell told us about, and used it on you."

There exists a counter-curse of unknown incantation covered in the Updated Counter-Curse Handbook, Second Revised Edition, and it is presumed a Pepper-up potion will cure the effects as well.
Quirinus Quirrell mentioned it to his first-year class in 1991. Ron Weasley threatened to learn this curse, then use it on Hermione Granger and Neville Longbottom if they got him and Harry Potter caught roaming the school at night on their way to a duel with Draco Malfoy. In the same school year, Harry Potter fell ill when Peeves used this curse on him. Harry had to look for Updated Counter-Curse Handbook in the library to perform the Counter-curse.
"Ad Nauseam" is a Latin term meaning "to the point of nausea". This implies that the curse makes one produce mucus to the point of them feeling physically ill.
