A true madlad is a combination of fearlessness & a total lack of common sense & self preservation. Always a contender for either the Darwin Awards or a prison sentence. Something along the lines of going on a bulldozer rampage in protest, booby-trapping a cabin built on land without a permit, ice fishing with dynamite, or attempting to do yoga on the ledge or flag poll of an apartment complex.
Only an absolute madlad like Inspector Zenigata would jump onto a race track during a race in an attempt to arrest a driver.
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.
