Pants vs. Trousers

Colleague: You wore a dress today?

Me: No, I'm wearing pants.

Colleague: (smirk)

Me: (oblivious)

Colleague: It makes me laugh when you say pants.

Me: huh? (wondering if it has something to do with my accent)

Colleague: Pants are what you wear under your clothes.

Me: huh?

Colleague 2: We call them trousers.  

Me: So what are pants?

Colleague 2: You call them underpants.

Me: Oh. Underwear. Ok. 

P.S. I'm still not sure why they refer to them as pants, but I guess Americans have a 

lot of names for the articles of clothing to be worn underneath your trousers.

P.P.S. Yes, I'm easily amused.  That's why you love me.
