Pedantry!

Ok. So ive notised All da grammor warrior's on 'ere.
Being a fellow pedant, I thought we should have a whole thread for letting out our grievances.

For starters:
Brake - Something which stops your bike.
Break - Something which happens to you bones if you don't have the above.

If you're such a 'pedant' then why do you think this is a grammatical error? I hate people who missuse the word grammar.
