A person who is stupid or does stupid moronic things. Like fall face first into a wall whilst trying to put on slippers... Most flidoid tends to be of a small height with a 3 inch nose.
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.
