Idiom Watch

• That's my speed - You instantly picture Steve McQueen in place of whoever utters this phrase, and he's a cool dude who drives fast (which is itself a cool thing to do), so you want to match his speed. That's what separates this phrase from generic "I like ____" statements: it implicitly invites the listener to agreement, if only they would step on the gas to catch up, or equally, one supposes, the brakes to chill out.
• Walking around money - Nothing says class like old timey political grift, and this phrase connotes the fattest of ward bosses doling out dollars in exchange for votes on the correct side of the ballot. Try it out on your partner the next time you need a couple bills from your (ultimately, if not explicitly) shared bank account but forgot to swing by the ATM before meeting them at the bar, and see if it doesn't put a smile in the corner of their mouth.
