"Now for your "Transform", whenever you turn on, you will regenerate into a completely different person like the show called 'Doctor Who'," you answer to your girlfriend as she laughs.
"Teeheehee... wow, that's... well... pretty nerdy, honey. I didn't realize you are a fan of Doctor Who." your girlfriend replies as she's teasing you. "I bet you're a Doctor Who fan after all, aren't you?"

"Umm... babe... you might as well look at your hands, they're growing..." you tell your girlfriend as you look at her glowing hands.
"Oh my god, it's happening." your girlfriend responds.
"Babe, did you just turn on?" you ask.
"Well, yeah, I guess. I am regenerating hun. Just like you just said." your girlfriend answers. "And why don't you just stay back while this... is... going to... get... Aaaaahhhhhh"

It's so bright that you can't see her body as she's transforming... or should you say regeneration. So the 'Transform or Dare' actually worked, your girlfriend did regenerate. 50 seconds later, when your girlfriend's regeneration was complete, her whole body stopped glowing as she was no longer your girlfriend, she was now...
