What if I'm sick of hearing about the Jonas Brothers?

OMG I’m really tired of my girlfriend talkin’ about those stupid jonas brothers. I don’t know why she talks about them. She says Kevin and Joe are so hot and Nicks looks like he belongs across seas. No offense to the chiness but I think you lost a cople of people in vietium. It’s getting stinkin’ agrovating. I feel like I’m ‘bout to dump her, which I really don’t want to do. I mean shes freakin’ HOT!! I like this gril that I’m with, but “No Bro’s” are getting in the way. Every time I laugh at the fall Joe had on stage that time, even though she hates joe, she gives the the stinkin’ don’t-talk-about-that-or-I’ll-slap-u look.I already got slap twice lol. It’s so easy to fit that in with her friends. I’m basically no nothing about the joe bros. all I know are the names, that she calls the the joe bros, and there touring with Miley Cyrus. And some girl named Hannaha Montana, which I never heard of. So, What should I do? Dump, Hold out, continue to get slaped or stand up for myself. Or give me some topics I can talk about that won’t get me slaped or make me sound G.
