Dunkleosteus 

A prehistoric fish that lived during the late Devonian period. It had thick armor plates of bone over its head and neck for protection.

The teeth of Dunkleosteus were fearsome sharp blades of bone. They could easily slice through the armor of other hard-bodied animals.

Some fossils of Dunkleosteus have bite marks from the teeth of other Dunkleosteus. So these massive fish were probably cannibals.

schmegegge 

Yiddish slang word meaning bullshit, baloney, hogwash, nonsense, crock of shit or hot air.

I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
