Do you think I should troll my gf in league of legends?
Why are you going to troll her? Are you upset?
Yes, I'm upset because she never listens to what I tell her.
I don't think you should troll your girlfriend in League of Legends because it's not very nice and she'll probably get upset. If you want her to do something differently then you should let her know in a polite way, not by being mean to her.
I have to troll her. The plan is to teach her a lesson.
League is a real stressful game I know, but when your girlfriend is there shouldn't you want to try to have fun? It will just make both of you feel bad by letting these negative game experiences affect you. How about playing together in an unranked match so you can relax instead?
