Kogan
It is the bromance name for Big Time Rush's Kendall Schmidt and Logan Henderson. It's the most popular 'ship' in Big Time Rush and they're like brothers-best buddies and knew each other before the formation of the band. They often hang-out and go on vacations together and share a special bond compared to other members of the band.

Rusher 2: Is that even a question? Kogan all the way.
Rusher1: Oh yeah, I don't think any Rusher can deny the special bond that they share!
