These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Memetic Molester: In the final short, a beetle in the walls has this small conversation with Toast Boy:
Beetle in the walls: I've been watching you, little toast slave... In the shower, yes? Becoming quite the young gentleman, aren't we, if you know what I mean.
Nausea Fuel: Anything having to do with the grandma. Particularly "Give granny's gash a moisten with that cream. Mind out, there might be a few loose kernels down there." The "kernels" turn out to be beetles.
I Am Not Shazam: Though "Toast Boy" is the main character's given name, "Spoilsbury" is never mentioned.
Squick: Almost everything, particularly the grandma and some of Toast Boy's nightmares. Especially the one where he watches two human-size beetles have sex, and then as two beetles rape his grandma.
Ugly Cute: Toast Boy and Liache count, mostly because both are on the verge of woobie status.
