Johnny Brown Pants

The condition of having brown stains, or skid marks on your underwear. May also be used a locker room taunt by young children, or at home by siblings.
Kiddo, you've got one serious case of Johnny brown pants.

Brown Johnnies

"Oh, man, I gotta make Brown Johnnies in a hurry!"
Also, if you have the runs, you can say,

"I shouldn't have eaten that hot pocket. I can feel the Runny Johnnies coming."
