(Fur-sh-new-gul) To take from one another, knowingly or unknowingly, in a friendly context generally with the intent of returning. Similar to mooch, yet has more of a connotation of taking property instead of borrowing. However, fershnoogle never refers to a serious case of theft; the fershnoogled property is generally of very little value.

Also, a fershnoogler is one who fershnoogles.

Very closely related with the word filch.
