These are some phrases my friends or co-workers use that I like but cannot use myself without sounding weird:
"all up ons"
Ex., "He was really flirting with her, he was all up ons."
Ex., "I like to go on vacation with the Iverson family, they're a hot mess."
"rickety old witch"
Ex. "Come to lunch with me, you rickety old witch."
Ex., Person 1: "Uh, there aren't any free cookie samples at Zarro's today."
Person 2: "Daggers!"
I'm going to try and use "hot mess" more often because it sounds so gross! Science fact.
