Brollercoaster 

A period of time where two bros are so close, that it seems that they are never apart.

"Dude, you and Bill have been chilling together alot-didn't we used to think he was a douche?"

"Man, we were so wrong about that-I love the guy. He and I are riding the brollercoaster together now."
