At Arizona state university, the Manzy challenge refers to a well known challenge that guys try to sleep with one girl from each floor of manzanita hall in one year, a total of 15 girls.
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.
