While you are working on your PC and some guy comes up looking over your shoulder and his junk bangs into your shoulder. Or maybe a barber leans too close while you are under the shroud in a barbers chair, "junking" your arm or elbow that is rested on the barbers chair arm rest. You would at this point exclaim, "How 'bout hangin' back, ya jammin' my frequencies!"

Sam: Wow, I can’t believe we just won that relay race!
Cat: we did it Joe 😭😭
