Why does my hand suddenly smell like dirty band-aid?

Question

and my coffee smells like a dirty dog took a bath in it

Answer 1

Ah yes, you recently took a dirty band-aid off of your finger, and when you went to throw it away, Fido sampled your coffee. He didn't like it, either. It smelled like clean human.

Answer 2

You haven't washed the recently.

Answer 3

Quit Using Coco Rico. Keep Your Nose Clean, You Nasty

Answer 4

You might have a sinus infection that affects your sense of smell.
