Halp me.

What's the quickest way to get rid of a girlfriend you're bored of?

quick way, just go up to here and say these words "I fucked your sister/mother/aunt/bestfriend/daughter/petgoat/cat/uncle/brother/wtf ever. and walk away.  She will never want to see you again.  Just one of these is sufficient for this, but if you really want to go big say them all.
