Go ahead and laugh at these, I don't mind.
"That's what she said" - People know I'm depressed or sick if that doesn't come out of my mouth at some point, nor will my transition stop me from saying it.
"Giggity" - This is less of a personal one, and more one that me and my group of friends (mixed gender and races) say anytime someone didn't think of how they worded something.
"Phrasing" - I stole this from the show Archer, see "Giggity" above.
As for a Jenni original: "It's bugging me nuts!" This was an unintentional portmanteau of "It's bugging me" and "It's driving me nuts". I was overworked, super tired, and my ex asked me why I was upset by something a family member was doing. It lead to lots of laughter and becoming one of my sayings.
