 Are you sure you don't mean a cascading menu ?  A tearoff menu gives the user the ability to tear off the menu into a new top level window.

The following example illustrates the difference:

from Tkinter import *
r = Tk()
m = Menu(r)

# Create a cascading Edit menu
editmenu = Menu(m, tearoff=0)
editmenu.add_command(label='copy')
editmenu.add_command(label='cut')
editmenu.add_command(label='paste')

# Create a sub menu of the edit menu and use tearoff option
testmenu = Menu(editmenu, tearoff=1)
testmenu.add_command(label='option1')
testmenu.add_command(label='option2')

# add the sub menu to the editmenu
editmenu.add_cascade(label='test', menu=testmenu)

# Add the edit menu to the menu bar
m.add_cascade(label='Edit', menu=editmenu)


# Display the menu
r.config(menu=m)

r.mainloop()
