I'm an American and I have always used the phrase "toasted cheese" rather than "grilled cheese". Also, I tried entering "stroller" for "buggy" because, honestly, I don't know anyone who uses a "baby carriage", that's something that I would expect to see in an antique store but not actually being used.
Buggy = stroller, pinafore = apron (first and foremost). And I was thinking about crash test dummies and similar, so to come up with pacifier was nigh impossible.
Rota definitely does not mean carpool! It's pretty much the same as a schedule. Typically timetable is used for school/university schedules, and rota is used for the work place, as in "I'm rota'd to work next Tuesday". Or at least that's how myself and everyone I know uses those words...
As far as I'm concerned a ponytail is a ponytail on both sides of the Atlantic. I've never heard the word bobble in that context. A bobble is a small ball of fabric used as decoration - for example bobble hat.
Never heard of anyone refer to a stroller as a baby carriage.
Rota = carpool... when?
