Your mileage may vary
From Wikipedia, the free encyclopedia.
Your mileage may vary is a truism, frequently abbreviated in e-mails and Usenet postings as YMMV:
1. It may work differently in your situation.
2. It may work differently on your computer.
3. This is just my opinion/taste, your opinion/taste may be different. (Example: "It's a very popular name. For that reason alone I wouldn't choose it. It's 'trendy'. YMMV, of course.")
