Derives from the Katy Perry song, "Hot N Cold"

When a heterosexual girl kisses another girl just to try it or is too drunk to realize they are kissing another girl.
Girl 1#- Did you hear about Suzie's Katy Perry Moment at the club last night?
Girl #2- What are you talking about? Isnt she with Dean?

Girl #1- Having a Katy Perry moment means she was too drunk to know she was kissing another girl,or maybe she just wanted to try it.

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.
