fellony

A serious crime that either is caused by someone's falling, or causes someone else to fall down.

A "fellony" can also refer to someone's illegally/unethically cutting/breaking down (i.e., "felling") a tree or other vertical object. Ordinarily, a classic example of this act might be the famous (or infamous!) tale about the tomahawk-wielding young George Washington, but it turns out that this narrative was just a myth (well, I must admit that I HAD always kinda wondered how "da great G.W." could have done all the awful things he was known for --- such as wrongfully jailing farmers, and keeping and disgracefully mistreating slaves --- if he was such an "honest" and "truthful" soul as a child!)) perpetrated by an overzealous newspaper-journalist, so I guess we would need to look elsewhere for a true and valid example... maybe the funny Echo-brand chain-saw ad, where the super-excited dude was so eager to try out his new Echo chain saw that he mindlessly cut down a neighbor's tree, and then when said neighbor confronted him about it ("That's **my tree** that you just cut down!"), the imperturbable miscreant sunnily replies, "Oh, no problem --- glad to do it for ya!"
