A term often used by those living in the North-Eastern United States, where rapidly changing winter weather creates slippery conditions for pedestrians without warning. Similar to taking a "wicked shitter," going "ass over tea kettle" describes the motion of the body as it somersaults uncontrollably on a driveway or down a set of basement stairs, for example. The tea kettle is valued during cold winter months and is used metaphorically to assert that something important (along with one's ass) has been damaged in the fall.
Not realizing that the driveway froze over, I went ass over tea kettle while goin' out to get the mail.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
