When referring to a Bellatrix Lestrange/Voldemort pairing from the Harry Potter series
I was reading a Bellamort fanfiction in which Bellatrix and Voldemort make out with each other!
Harry Potter fanfiction term where Bellatrix Lestrange and Voldemort are a couple, having sex, and or have feelings for one another
Bellatrix and Voldemort have so gotten it on! Hence the term Bellamort.
