"Yes honey."
"#%()#) where is my money?!"
"Not the contextually appropriate way to say that."
"It's cool yo."
Friend: Can you tone down the politeness a little? It's... weird.
Me: I am afraid that I cannot.
Friend: Creepy dude.
Me: Begging your pardon but I am linguistically incapable of it at present.
For "Got a sec?", to a close friend I was interrupting:
Contextually appropriate: ちょっといい?
Me: ちょっとよろしいでしょうか?
It's not wrong if addressing e.g. bucho at the office but yeah I weirded people out a lot.)
