You were distracted at the wheel, weren't you? You really should keep your eyes on the road, sir. What were you looking at? The same word is used to mean both armpits and, in a more general sense, the side, the flank. The term used is literally "driving while looking to the side", but could also be interpreted as "driving while looking at armpits".

I'm sorry... I saw your armpits... A different kanji is used which is more specific to armpits as opposed to the general meaning of "side".

Yes, I could tell that, and I'm asking what you were looking at.

No, like I said, your armpits...

...Are you trying to be funny?
