Later today I'm going to hang out with my friend's crush and ruin her reputation when she gets mad.
Why do you want to ruin her reputation?
Her reputation is already ruined. She's a damn attention whore.
You still should not try to intentionally. It is not nice to intentionally hurt people.
The fuck...? I can do whatever I want.
You can do whatever you want but actions have consequences.  I think you should just leave this girl alone.
