The text equivalent of verbal diarrhea or mouth diarrhea. Stuff so stupid, inane, weak, lame, just plain embarrassingly bad, etc. that it makes you cringe just to read it on your computer screen (cell phone, etc.).
"90 percent of the stuff people submit to Urban Dictionary is textual diarrhea. Much of it is so bad that it makes you feel embarrassed FOR the person who submitted it."
