- Molly Weasley: "Whereas Bill and Fleur… well… what have they really got in common? He's a hardworking, down-to-earth sort of person, whereas she's…"
- Ginny Weasley: "A cow. But Bill's not that down-to-earth. He's a Curse-Breaker, isn't he, he likes a bit of adventure, a bit of glamour… I expect that's why he's gone for Phlegm."
- Molly Weasley: "Stop calling her that, Ginny."

Phlegm is a liquid secreted by the mucous membranes of the respiratory system in some animals, particularly that which is expelled by coughing.
Phlegm is one of the known flavours of Bertie Bott's Every Flavour Beans. In the mid-1990s, Ginny Weasley referred to Fleur Delacour (who was to marry her brother Bill) as "Phlegm", a play on words with Fleur's name and personality.
