An event,
meeting, happenstance, occasion or other occurrence that warrants a vague
reference or subtle deception when
somebody asks about it. Often used during phone conversations when one person is in a place they shouldn't be.
"Where were you last
night? I called you
like, I don't know, 15 times!"
"Well, I had this whole schmagoola over at
Lenny's place, and I couldn't tear myself away from it, babe, y'know?"
or
"Yeh, ma, it's fine... No, just another one of their schmagoolas, nothing in particular, some wine and cheese, the usual pack of twead-coated sycophants" (He's actually at a strip club doing lines in the bathroom)
