I was at soccer practice and one of the guys on my team's girlfriend showed up. This was sort of surprising since we thought he (we'll call him H) was gay and dating his best friend(we'll call him E), who's another guy on the team, but we were all nice & kind to the GF. However, this chick is as annoying as kindergardener on crack , and we quickly realized that the best friend hated her guts. The GF was rolling around in the grass and doing weird stretches and was acting like a drunk toddler or something like that. The weird thing was, the girlfriend looked really, really familiar. Then I realized she looked just like her boyfriend's best friend. Their faces were basically the same, their hair color was the same, even the way they walked (which was very feminine) was the same. 

The unfortunate thing was, the best friend clearly hated her. Since he was goalie, he had a lot of time to give this chick a death stare. During the water break, he looked at her and H, and then made gagging noises. And on the school bus, he stares at her with some mixture of anger and jealousy. It was kinda funny, because his reactions and his friend being completely oblivious were hilarious, but also a little sad. Poor guy, I guess he misses us yelling at him about his "boyfriend".

Tl;dr guy on team brought his gf, his best friend completely hates her, but the gf and the best friend look exactly alike.
