P+TY

P+TY, abbreviation of Please and Thank You, is how you graciously make a request (please) for an action and proactively express gratitude (thank you) for the taking action on the request. It was popularized by Ron Swanson, a devout stoic, who's gruff exterior was belied by his need to be polite in every instance.

Just give me all the bacon and eggs you have, p+ty.

NFN

Not for nuthin' -- This is the New York City equivalent of "respectfully speaking" or "all-due respect", warning the receiver that they are about to get a dose of unvarnished truth that they might find insulting, but isn't meant to be insulting.

NFN, what you said the other days makes you a little bit of an asshole.
