2. On an ICP album and one by Limp Bizkit there are songs that actually tell you how many times they use the word "fuck". It's over 80 times each! Now that's a case of major diarrhea of the mouth.
3. Lee is watching TV and an ad for some airline is on. The host just keeps on blabbing on and on. He's offering reduced air travel rates only IF Lee schedules his flight on certain times of day, on certain days of the week, using a certain credit card, showing proof of ownership of a new Subaru car and he must've kissed Marilyn Monroe. So many conditions! Lee thinks that the ad host has diarrhea of the mouth - all he's saying is total SHIT.
4. Kid Rock should be renamed Kid Ego. He's got absolute diarrhea of the mouth.
