When a person has to a gets a little too drunk at a Jewish function, including but not limited to a Bar Mitzvah, Passover Seder, or bris.
I had four bottles of manischewitz at David's son's bris, and punched the moil for touching my nephew. I was definitely Mazel Tossed.

We did 8 shots of potato vodka and got Mazel Tossed and Ezra's Hannukah party.

Joshua likes to get Mazel Tossed and annex parts of Palestine.

Yaakov got Mazel Tossed at Noah's Shabbat Seder and threw up Matzo balls all over my Yankees Kippah.

Get the Mazel tossed mug.
The act of using a bagel stuffed with cream cheese and lox into the whole and masturbating with it and then exclaiming "Mazel Toss!!" while ejaculating. Various sexual fantasies can be fulfilled with using different types of bagels.
Simon: I thought I heard someone scream in pain and turned out it was just Saul. He was finishing a Mazel Toss when I walked in on him. Disgusting! He used the rest of my lox too.
Bernie: Nightmare! Was he using pumpernickel again? He likes 'em dark.
Simon: No, but it was a mini bagel. I think he like 'em young too.
