Here you go - I know how you hate not knowing what words mean:
Noun
1. tripe - lining of the stomach of a ruminant (especially a bovine) used as food organs, variety meat - edible viscera of a butchered animal honeycomb tripe - lining of the reticulum (or second stomach) of a ruminant used as food
2. tripe - nonsensical talk or writing codswallop, folderol, trumpery, wish-wash, applesauce, rubbish, trash drivel, garbage - a worthless message jargon, lingo, patois, argot, vernacular, slang, cant - a characteristic language of a particular group (as among thieves); "they don't speak our lingo"

Dictionary:
tripe
(trīp) pronunciation
n.
1. The rubbery lining of the stomach of cattle or other ruminants, used as food.
2. Informal. Something of no value; rubbish.
[Middle English, from Old French tripes, intestines, tripe.]
That would be definition #2 in both cases.
