when you have to shit really bad, but you aren't close to a bathroom, the turd starts to come out, but you suck it back in your ass as you walk swiftly to the john. like a gopher popping out of a hole.
when you use vaseline to cover an entire gopher and then let it slip up into your ass cavity. this can be excruciatingly painful or immeasurably pleasurable depending on how big your asshole can open up.
boy! get my tub o vaseline! ima lube this damn gopher up and teach him a lesson once and fer all! time fer some gophering...
