When a man and a woman essentially switch places sexually (hence the term "switcheroo"); the man does not include his dick in the sexual act, but rather takes a strap-on cock in the ass from the woman. Note the "big" in the term. There is a difference between a "big switcheroo" and a generic switcheroo. A generic switcheroo is simply a male individual taking a strap-on in the ass from one (or more than one, Jesus, I'd hate to be that dude :/) female. For it to be called a "Big Switcheroo," the act itself is much like the generic switcheroo, BUT before the act occurs, there is a formal ceremony in which the man and woman partake in, that switch each others roles in spirit for the next hour. This ceremony verifies the soon-to-happen act as "big". Traditionally, a flock of Doves is released from a basket immediately following the ceremony. However, in southern states of the United States, Big Switcheroo-ers tend to prefer freeing a flock of cocks from a cage (no pun intended).
Guy: Hey babe, you ready for tonite? The Big Switcheroo! ;P
Girl: mm, yeah babe, did you call the dove-releaser guy and set up an appointment for us?
Guy: Oh fuck, babe I thought YOU said you would handle the scheduling with the dove-releaser? Now it's, it's ruined! It's just going to be a switcheroo :(
Girl: I'm so mad at you I'm going to strap-on the fuck outta you right now. "Big" switcheroo or generic.
