All dialects of English are on topic and welcome. Just make sure you give sources for your definitions when they come from dictionaries and cultural and geographical background if your answer is based solely on personal experience.
I would, however, avoid calling a something absurd just because it doesn't conform to your own experience and your own cultural background. Many words are used quite differently in different dialects and all are as valid as each other.
You are free to spell using BrE or AmE customs. I don't know of any other choices off the top of my head, but if there are and are considered standard in any part of the English speaking world, then they're welcome here as well.
Our top users are from both sides of the pond (and beyond), there is no one dialect or style we're supposed to cleave to.
