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.
Crosses the Line Twice: Stephanie puts a shotgun in her mouth and blows off the back of her head? Tragic. Stephanie is still alive despite missing half her skull and the associated contents? Horrific. On the way to get help the delirious Stephanie starts giving a blowjob to the driver, who realizes that he is actually penetrating the ragged hole in the roof of her mouth? Hilarious.
Kevin gets not one, but two blowjobs from Stephanie after she blows her brains out. He is equally turned off both times.
