Pants (for non-Americans very annoying)
Handphone !!!
Erm, America isn't the world, you know...
Pants are perfectly alright - wear them right in the first place and don't be caught with them down.
What's wrong with handphone - describe the gadget perfectly. OTOH, what the hell is a cell phone? A handphone you use behind bars? Or one made of plant cells or human corpuscles?
