freshman challenge 

Typically done by seniors, but any upperclassmen will do. The Freshman Challenge is the act of an upperclassmen (typically male) having sexual intercourse with a freshman (typically female).
A variation on this challenge is how many freshmen one can perform intercourse with in the school year (summer vacation does not count as there are not any official freshmen until the school year begins)

Damn, I think John's trying to do the Freshman Challenge with Amanda!

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.
