First-year fridget 

Someone around the age of 12/13 who has not yet had a meet/shift/french kiss. Irish slang.
In the Irish educational system, after graduating from primary school (about 12 years old) you move onto the first year in secondary school. Therefore a first-year is just your average pre-teen. However, by that age, the best way to be popular is to not be a fridget. A fridget is someone who has never "met" (also Irish slang.) someone. In most cases, people are slagged for being a first-year fridget, but only lightly by friends. Being a first-year fridget isn't bad, but boys typically try to get a meet before first year to avoid the situation altogether, and also in an attempt to show off to their friends.

"Hey, in your school do you get bullied for being a first-year fridget?"
"Nah, yer grand."
"Really?"
"No mate, you're screwed."
"..."
"Don't worry though. Just go to a disco or something. You'll get a meet there.

"Thanks, bro."

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.
