Big Stranger Rodeo 

An instance in which a small person, encouraged by a group of friends, jumps on the back of a comparatively large stranger, or person they do not know. The intent is to stay on the stranger for 8 seconds while the large, strange person ponders why someone is trying to get a piggyback ride he did not consent to. Abbreviated "BSR."

Friend: Look at that guy over there!
Smallguy: He's gotta be at least 6'1"
Friend: I'm feeling some serious Big Stranger Rodeo

BigStranger: Whaddafuh?
