I consider myself a fisherman. I fish for stereotypical nerdy men who also likely smell pretty fishy.
How do you find such men ?
I can use some kind of bait or something for that (laughs)
It's fine to have a sense of humor about things. You might want to work on that smell though.
What? Women consider it sexy. It's called I smell of a man.
The metaphor you used is kind of inappropriate. It's not funny to compare nerds with fish. You seem to have a good sense of humor so come up with something that's not offensive.
