don't believe all those other little girls who gave their definitions of tripe.
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.
The word tripe gets confused with the words trifle and trite -usually by dumb, urban illiterates. Enough time passes and the word becomes cool to use as stupid jargon, while typically wearing clothes several sizes too large.
