What you call your friend after he does something extremely dangerous and stupid (i.e. jumps off the house on a Razor scooter and attempts to land in a kiddie pool full of instant jello) and survives.
Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".
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.
