boyfrienditis 

an unfortunate condition where a girl, who might have actually been a decent friend/person prior to getting a boyfriend, turns into a huge douchebag.

-becomes completely absorbed in her relationship

-stops spending time with her real, genuine friends and ditches them to spend time with her boyfriend (who is usually a huge asshole) and his dumb bros

-gives into her boyfriend's every desire and hangs on every word that comes out of his mouth, acts like his property

-makes up elaborate lies to get away with her shitty behavior

-tries to give other girls advice about guys

-doesn't care about anything other than her stupid boyfriend

-will spend innumerable amounts of hours watching her boyfriend and his friends play video games, but won't answer calls or texts from her actual friends

-will likely fall on her ass all alone after the break-up because she has alienated all of her real friends

I used to hang out with Chelsea, but she got awful boyfrienditis when she and Sean started going out. I just stopped trying to be her friend.

Boyfrienditis 

A curious condition where a woman is completely obsessed with her boyfriend to the point she no longer cares about anything else. School/uni, hobbies, friends, career etc. no longer seem important to a woman infected with boyfrienditis. It is usually recognised by the exessive use of makeup and non-stop talking about the boy.

Jill's boyfrienditis caused her to not study for her exams.

The way the boyfriend teaches his girl how to adopt his personality and weird behaviors so he isn't the only awkward person in the relationship. This can be e.g. weird language/ word choices, behaviors and memes (especially when she never used them before your relationship).

*girlfriend who doesn't play video games has a gaming-internet-junky-boyfriend uses gaming expression*

her: "kek" / "lmao" / "Such a retard"
