Word chanted in "Animal House" (4)
I believe the answer is:
toga
'word chanted in animal house' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for toga that I've seen before include "Graph's y value" , "Roman tunic" , "Got a cloak for an old Roman" , "Roman dress" , "Roman male garb" .)
