False Katy Perry Boner 

When you hear a song by Jessie J and you mistake it for a song by Katy Perry, which gives you a boner.

I used to think that the song "Domino" was sung by Katy Perry, which gave me a huge boner when I would hear it. But then I found out it was Jessie J, so it was a False Katy Perry Boner all along.
