One of those irritating couples that think they have to do everything together. Often won't hang out because their fellow biker has already made their plans for them. They may also coordinate outfits. The name suggests that they even choose their mode of transportation to feed their habits.
Ryan had to check with his girlfriend before he could RSVP, so I doubt he'll show. No doubt she already has plans for him to watch the Bachelorette or something. Fucking tandem bikers.

Reverse tandem, is facing each other.

Bro 2 - "Fuck yea Bro!"
Shots down and they both start to puke off the side of the balcony onto the one below it resulting in the act of tandem puking
