Here's a little ditty about a slut to outslut all sluts

I don't like you.
I don't like you in the slightest.
It's not only because you remind me of someone I used to know,
But it's also because you could outslut the entire population of sluts on the planet,
You're more tossed than a salad on a gay man's arse,
You're even more up yourself than that person you're going out with,
A leather boot has more intelligence than you could even fathom.
Not even staring into the sun for a day would be able to cleanse your image from my eyes.

I can keep going but I think I've mentioned all that I want to at the moment...

10 points to whoever can guess of whom I wish I wasn't thinking of...
