similar to a wingman, but not exactly the same. A wingman suggests that your job is to distract the friend of a girl while your friend goes in for the poops. When being a sidepoops, you job can be that, or you can just be coming along for some easy poops in a pre-set double dating scenario.
"Dude, if she has a friend she wants to bring, I'll be your sidepoops."
