"At that moment Neville toppled into the common room. How he had managed to climb through the portrait hole was anyone's guess, because his legs had been stuck together with what they recognised at once as the Leg-Locker Curse. He must have had to bunny hop all the way up to Gryffindor tower."
—Description of the curse[src]

The Leg-Locker Curse[4] (Locomotor Mortis)[4], also known as the Leg Locking Spell[5] was a curse[1] that bound the legs of the victim together.[4] It was most often used by experienced witches and wizards in duels, or in friendly wizard races.[5] This curse was one of the dark charms found in the Dark Arts spellbook Curses and Counter-Curses by Vindictus Viridian. There existed a counter-curse of unknown incantation; Hermione Granger used it to reverse the usage of the curse Draco Malfoy used on Neville Longbottom.[4]

Etymology
