Katy says in the song “I kissed a girl and I liked it [...] I hope my boyfriend don’t mind it”. Katy, honey, I am sure your boyfriend do not mind it but, please, the next time, let him watch (or even join you both).
Anyway, I’m not here for talking about Katy, her lesbian kiss nor his boyfriend. I’m here because of this song. The first step is to change girl/boy. This way, you get “I kissed a boy”
Ok, it is a parody, but, IMHO, it’s a poor one. I prefer Rick Reigns’:
“I knew it was wrong but it felt so right to know I was messing up your night” is a great sentence I hope not to hear in my life…
