tripe is stomach lining of animals. it's delicious stuff, a nice chewy alternative to all the other stuff out there. goes great with vietnamese pho, and it's awesome as a chinese stir-fry.
Tripe: a replacement word for shit when used for someone's speech.
(I made it up coz Tripe sounds like nasty dog food, haha)
Person 2: "Quit talking tripe.. You ain't ish!"
