I'm going to stir up shit with an acquaintance and his girlfriend
Why would you want to cause problems with them?
I just want to because I can, and his girlfriend is such an easy target.
You should not pick fights with people just because you can and because they seem weak to you. If you behave in such a hostile way, you will lose friends and gain a bad reputation. You should try harder to get along with people instead.
That's lame for you to say.
I'm just saying that picking on people for no reason is mean and you shouldn't do it.
