laddusaw-syndrome
When a guy enters into a relationship with a girl and subsequently alienates his friends. examples of this include, but are not limited to; constantly ditching your friends for your girlfriend, letting your girlfriend wear fraternity letters that she hasn't earned, generally siding with your girlfriend even when she is blatantly disrespectful to your friends. The worst part of this syndrome is that the girl in question is NOT worthy of these actions.
When brian's girlfriend yelled at us for no reason he took her side, he must have laddusaw-syndrome because why else would he put hoes before bros?
