A phrase often usd by people who don't really know what they're doing.

This catch phrase was often used by the 80's TV cop Sledge Hammer right before he does something that results in some sort of catastrophic event or disaster.
Captain Trunk: Sledge, you cannot disarm that nuclear bomb!

Sledge Hammer: Trust me, I know what I'm doing.

(A nuclear explosion ensues thus ending the season finale of Sledge Hammer)

I didn’t know

The thing you say to someone when they thought you knew the secret language but in fact you did not know the secret language, they only thought you knew it because of that one time, a long long time ago, 8 years ago. Also, it would appear that said grump had a girlfriend, soooo.. what the hell am I supposed to do with that? 🤷🏾 ♀️
I’m sorry i missed our appointments, i can’t imagine how that must’ve felt, I’m sorry this comes off rude, crass or cold. I didn’t know. I’m sorry. How can I make it up to you?
