Oh No Wolverines

In FRIDAYS AT ENRICO'S one character's actions are described in the following simile/sentence fragment, which I have bowdlerized for your protection: "Like a wolverine, [pooping] on everything it could not eat." Oh no! Is that what wolverines do? Why didn't I know that, if so? I am not going to "fact-check" this. Why would the kids in RED DAWN want to call themselves Wolverines, and cry out "Wolverines!" at moments of victory? Is it a commentary on the defiantly wasteful consumerist society they are trying to revive under the very noses of their communist overlords? I'm going back to bed now, good night.
