The action of getting something taken from you by a "finch". This 'object' is generally something that is easily recognized as yours to everybody except for the finch. Before you even notice what is happening the finch will already be in possession of what was once yours. Finches are generally harmless entities.
"Jack totally just finched my burrito."
"He finched the ball from me in practice yesterday"
"I heard he tried to finch Chris' girl the other day."
Getting stabbed or shanked violently.
"You better shut up before you get Finched."
To be stabbed in such a way it reminds you of Kayla Finch from the United Fleet stories.

The act of rushing home to take a shit in your personal toilet, regardless of how many publicly accessible toilets are available within a more practical proximity.

"That was a long trip to the bathroom, Dude."
"Its not what it looks like! I was finching, so half of that time was travel."
