Weird, sickening, distasteful. Can be used as a noun or adjective.
Also: One who eats babies.
From Johnathon
Swift's satire,
A Modest Proposal, which outlined reasons for why we should
eat babies.
That ugly girl's display picture is such a
modest proposal.
Look Dude, the principal is trying to dance! That's so modest proposal!
I named
my hamster Modest Proposal after she got knocked up by a
gerbil and ate half of the offspring.
