"Hello. It's me. I want to break up with you, is that okay?"

Don't get in a relationship with them in the first place if you didn't like them...

Just because you're breaking up with someone doesn't mean you didn't like them. Not all relationships are supposed to be for the sole purpose of making it all the way to the end.

Straightforward and sincere.

"Say you'll see me again even if it's just pretend... Say you'll remember meee!!!!"

Tell them the truth, it'll suck but it's for the best

I'd sit on their face one last time.

Friend them on Facebook with a super hot, but believable guy. May take a few weeks to earn their trust, but basically you use what you know about the current boyfriend and make the catfish like all the same things. If you manage to swap nudes then it's simple; but otherwise you'll have to find something else where you can easily expose them for. Of course you never let them know you were the catfish so they look like the cheater. Worked for me. I even used the catfish to post the nudes on his Facebook and let everyone see he was a skank.

Just because you breakup with someone doesn't mean you never liked them tho. Feelings change, people change and sometimes couples just become incompatible.

Mess

buy them an horrible album
