If you high road someone, you attempt to undermine them with an unconvincing appeal to morality: "I can't believe she's high roading me for getting drunk one time when we all know she can't get through the day without Xanax." I learned this phrase from Rick and Morty and have subsequently noticed it comes up a lot. Probably because Rick is usually doing something unethical (at least by conventional standards). 

Today's phrase is "to drop a dime." It means to rat someone out to the police:   "That same unmarked car has been parked across the street for two hours. I'm beginning to think someone dropped a dime on us."  The image references the act of dropping a dime into a pay phone, ideally on a gritty side street in a 1920s hardboiled detective novel. If you're ever privy to snitching, be sure to use this phrase to convey your familiarity with the criminal underworld with effortless cool.
