What is the meaning of "roll" in this context??

Hi?

Yeah, uh... it's a two-day party, 'cause that's just how we roll. Uh, so, if you want to swing by, you know, it's casual. (how I met your mother S1 EP1)


I can't find the meaning of roll from dictionary.
is this the same as roll in rock and roll? or roll in winter roll around?

It means something like that's how we do it.
