flat four

A type of an engine configuration; there are four cylinders which are arranged in a flat opposing configuration. They're found in many different Subaru models (The Boxer Engine) and also found in classic VW Beetles.

Everyone panics & hides in their houses when it's snowing out, but not me, my world is flat; I grab my keys & head out to play in my flat four (4 banger)!

flat smile

The passive aggressive look you get from your wife when you haven’t done something or, asked for sex. It’s characterised by a straight mouth, with mildly pursed lips, a raised yet furrowed brow, and rarely any verbal communication.

Oh man, she’s given me the flat smile. I’m cooked.
