Why are there two images?

This trope is basically when something is so offensive that it's funny, right? Well I've seen this trope posted on works that don't fit that criteria AT ALL, with th trope linked here, but renamed something like "crosses the line so many times we've lost count" or somehting like that. But if it's extremely offensive, but not funny, than it's not this trope, right? Does that entitle me to delete it when it is listed on works that don't fit? I just feel the trope title is bieng misused is all.
