When someone posses the colon of a rhino that person is able to hold their crap much longer than an average person would be able to,until a toilet is readily available for their personal use.
Announcer: Aaron Rodgers, you and the Green Bay Packers have just won the Super Bowl, what are you going to do next?

Aaron: I don't know about the others but I'm gonna go drop a duece, I've been holding it since halftime.

Announcer: This game went into triple over time and you've been holding a dump the entire time, you must have the colon of a rhino.

Aaron: Thanks.
