C: Okay, brb, gotta go find pants (story of my life...)
L: LOL, that's funnier in UK English.
C: My American-ness confuses me now.
L: The pants = not underwear thing always confuses me.
C: OH, I see! See, underwear = underpants are interchangeable here, but never pants. Panties, perhaps. But that's specifically knickers. ... Sort of. We do have something we refer to as "knickers" but it's a specific sort of panty.
L: Knickers = women's pants here.
C: Wait, UK pants, yes? This is more confusing than cookies and biscuits.
L: In the UK pants are plain cotton underwear and little boys also sometimes wear pants.. and some grown men that shouldn't be allowed to exist.
