here in the north bay we say "your team" and point to a typically unfortunate looking person.
for example, let's say we're walking down the street and we run into this guy...
i would cringe, turn to you, acknowledge the absolute herendousness of this person and simply say "your team". this person is then added to your team. there's really not much more to it than that. and generally teams around here get too big to keep tally of. yeah, it's pretty dumb, but it can be pretty fucking funny.
oh yeah, we also call one another gay/faggot/homo etc. in an effort to degrade one another.
