In Disney's Hercules there's a scene (at 57:30 on Disney+, or on Youtube) in which Megara tries to convince Hercules to spend some time with her instead of doing whatever his trainer Phil planned for him. The conversation goes like this:
Megara: You sound like you could use a break. Think your nanny goat would go... Berserk if you played hooky this afternoon?
Hercules: Oh gee. I don't know. Phil's got the rest of the day pretty much booked.
Megara: Ah, Phil, schmill. Just follow me. Out the window, round the dumbbells, you lift up the backwall and we're gone.
(Phil is a satyr, which is why Meg calls him a goat.)
What does "schmill" mean? The only definition I've found is on Urban Dictionary, which says it means "a fat jewish person".
