I have no idea what's going on, but I LIKE it!
"I have the weirdest boner right now."Sometimes, someone will come upon something they don't understand, or simply cannot comprehend. Maybe it's two (or more) people engaged in something so Head-Tiltingly Kinky that it blows their mind. Maybe it is an Eldritch Abomination made of nothing but tentacles and gaping orifices. Maybe its Austalian-rules football. It doesn't matter. All that we know is that: A.) They have no clue what is happening. and B.) It's HOT! Strangely Arousing is a trope that takes people far beyond the brink of arousal, with no understanding of why.The confusing element doesn't even have to be sexual in ANY way. Nor does the character have to be one that responds sexually to everything. In fact, the trope works infinitely better if the inciting incident ISN'T indecent. Though if it is, it should be so far gone beyond "normal" sexuality it comes out the other side. Compare Head-Tiltingly Kinky. Note that Stupid Sexy Flanders is a very mild form of the trope, limited only to an unusual homoerotic sensation. Can overlap Fantastic Arousal, but only when a party witnesses it without understanding it, or to further drive home a sense of Blue and Orange Morality. Can also be referenced later as a Call Back when we later find the character has embraced this trope and turned it into personal Fetish Fuel. No Real Life Examples, Please!. After all, everyone is into something, and everything has someone into it.
